- Hi, I'm Ashley and welcome to Math Park.
Today we're going to see how the Denominator saves the day for a lady having trouble with fractions.
So stay tuned.
(upbeat music) (school bell rings) (kids cheer) - [Teacher] Get ready for a very special super-duper math class.
We're going on a field trip where learning math is tons of fun.
Our destination is the Math Park.
(upbeat theme music) (kids laughing) - Howdy, chipmunks.
Welcome to Math Park.
I'm park Ranger A. Rith Metic but you can call me Ranger Rith.
Math Park is a place where you can get a good deal on a kite, no strings attached.
You know, the work of a park Ranger requires keen senses.
And right now I smell birthday cake.
- Oh, Herman's cake looks absolutely beautiful.
(phone rings) Hello?
Hello darling.
Oh, you should see your birthday cake, it's... What?
You're bringing five people from the office for cake.
Okay, darling.
Uh-huh.
Bye.
Oh, no.
Herman is bringing five people from the office for cake.
I don't know what to do.
Help, help.
Will somebody help me please.
I'm terrified of fractions.
Help.
Please will somebody help me.
Help.
Help.
(suspenseful music) Please, somebody help.
Help, will somebody help me please.
I'm terrified of fractions.
(whirring sound) (whooshing noise) - Denominator to the rescue.
(whoosh of flying) (crashing and clanking) (cat meows) - Sorry about that.
I'm still working on my landing.
- Who are you?
- I am the Denominator.
(upbeat theme music) - Well, how can you help me?
- You have a problem.
You have a birthday cake and it must be shared equally with a group of people.
- How did you know that?
- Supersonic hearing?
- Oh, what else did you hear?
- Nevermind.
(drum sting) So let's figure out a solution to your problem.
How many people are coming to eat cake?
- Well, there's Herman, myself, plus five other people.
- Hmm.
So how many people does that make?
(upbeat music) I heard someone shout out seven.
- I didn't hear anything.
Well to be safe, let's use a calculator.
- Here, use mine.
Oh, okay, great.
Okay.
So let's see that's Herman and myself plus five people that makes seven.
- Correct.
Now we must slice the cake so that there will be seven equal pieces.
- I'm so glad you're here to do that.
I mean, I can bake a cake, but when it comes to slicing it, sheesh.
- That's why I'm the Denominator.
(upbeat music) I take whole things and I cut them into equal pieces.
Now stand back.
(suspenseful music) (laser buzzes) - That's amazing.
One, two, three, four, five, six, seven, eight.
Hey, there are eight pieces here.
I wanted it to be seven pieces.
- Well, come on, sevens.
Cutting things into seven equal pieces.
That's hard.
- But you're the Denominator.
You're supposed to know how to do things like that.
- I don't know.
Maybe I was absent from Denominator school the day they taught us how to cut things into sevens, but I'll tell you the truth.
That cake is cut into equal pieces.
And each one of those pieces is a part of the whole cake.
That means each piece is a fraction.
- A fraction?
- Fractions are equal pieces of something.
- I see.
Gee, I really appreciate your help, but what am I going to do with this extra slice of cake?
(suspenseful music) - Mmm, well, haven't you heard of my fee?
I charge one slice of cake for my services.
(cackles) - I had a feeling you were going to say that.
Enjoy.
- Thank you.
(upbeat music) (phone rings) - Hello.
It's for you.
- Hello, Denominator here.
What's that?
I'm on my way.
I'm off on another mission.
Catch you later.
Denominator to the rescue.
- Bye.
Thanks for all of your help.
Look out for the telephone (boing) line.
Oh.
Now how's he going to get himself untangled from this situation?
(upbeat theme music) - [Teacher] Fractions.
Fractions are parts of a whole.
That means when you take something like a cake or a banana and you cut it up into different parts.
- Well, Hey Ranger Rith.
How goes it?
- Why, I'm having a grand day except I'm feeling a little peckish.
Well, that means hungry.
- Oh, well I can help you out there.
Would you like half of my banana?
- Well, half a banana would really hit the spot.
- Luckily I just happened to have a knife here so we can cut it.
Here's your half, my friend.
- Not to be ungrateful Kiffen, but this is not half of a banana.
- You mean my half is bigger than your half.
- Well, that appears to be the case.
You see, one half is a fraction.
Both halves have to be the same size.
- Delicious thought.
I'll chew on it.
(upbeat music) - [Teacher] Equal parts.
- That's when you take something that's whole and you cut it up into parts that are all the same size.
Now let's take a look at this.
This is a circle and it's been divided into two parts.
Are both of the parts equal?
Yes they are.
Here's another circle, and it's also been cut into two parts.
Are the parts equal?
Yes they are.
And a third circle.
It's been cut into two parts.
Are they equal?
Oh, they're not.
And we have a square.
It's been cut into two parts.
Are the two parts equal?
Nope.
And another square.
How many parts is that?
Four.
And are the parts equal?
Indeed they are.
And a rectangle, three parts.
Are they equal?
Not at all?
- [Man] Mmm, two equal parts.
Hey, two unequal parts.
That's not fair.
- Okay.
Now I get it.
Mmm.
Mmm.
- I'm glad I could help you understand that.
It's part of my duties as a Math Park Ranger, to be all knowing and keep a keen lookout.
Good day, dear Kiffen.
Whoa.
(boing) - I guess you didn't see that banana peel.
- No I didn't.
- I guess you must've blinked.
(howling) - Oh, oh yeah.
Remind me to put bananas on the list of dangerous things not to step on.
Kiffen should have properly disposed of that in the trash can.
Well, now it's time to go somewhere safer.
That means the Math Park 'copter, where we're going to be flying over fields that have been divided into equal parts.
Come on, math chipmunks.
Let's take this bird into the air.
(helicopter flying) Now look down there.
There's a cornfield divided into equal parts.
How many equal parts do you see?
The field has been divided into four equal parts.
When we talk about fractions, they're called fourths.
Now let's see another field.
Now there's a wheat field.
How many equal parts has the wheat field been divided into?
The field has been divided into six equal parts.
We call those sixths.
Now here's a field of sunflowers that's been divided into equal parts.
How many equal parts has the sunflower field been divided into?
The sunflower field has been divided into eight equal parts.
We call that eighths.
Now let's get some more practice at naming parts of a whole.
(helicopter flying) - [Teacher] Three parts.
Thirds.
Nine parts.
Ninths.
Two parts.
Halves.
Seven parts.
Sevenths.
Ten parts.
Tenths.
And this one is not cut into parts at all.
It's one whole.
And now it's time to play Fraction Match, the fun game where we'll see who has the matching fraction?
Will it be Ivana or will it be Janet?
Let's find out.
Okay, ladies, choose your fraction picture.
(electronic beeping) All right.
Now let's take a look at those pictures.
Janet's rectangle is cut into five parts and Ivana's rectangle is cut into three parts.
Okay, let's look at the fraction generator and see who has the fraction match?
It stopped on fifths.
Who has fifths, is it Janet or Ivana?
That's right, it's Janet.
Way to go.
Round two.
Let's see who's going to win.
Okay ladies, choose your fraction picture.
(electronic beeping) There we go.
Now Janet has a rectangle that's cut into two parts and Ivana has a rectangle that's cut into six parts.
Okay ladies, let's see who has the fraction match?
Let's see where it stops.
Halves.
Who has halves?
Is it Janet or Ivana?
Wow.
It's Janet again?
Boy, is she lucky today?
Round three.
Okay, Ivana.
Let's see if you can score this one.
Find those fraction pictures.
Choose them.
(electronic beeping) - And, ooh, there we go.
Janet has a rectangle that's been cut into eight parts and Ivana has a rectangle that's been cut into four parts.
Okay, let's see who has the match.
And here it goes.
Let's see who's going to win this one.
All right.
Fourths.
All right.
Who has the match?
Is that Janet or Ivana?
Who could it be?
It's Ivana.
Congratulations, Ivana.
You won this round.
And Janet's you won the first two rounds, so you are our winner for today.
Janet wins the game.
Congratulations.
That was fun, girls.
(Japanese music) Hyah.
Hyah.
Fifths.
(bugle plays and trails off) - Did you hear that?
That means Math park is closing for today.
Until Math Park reopens, I salute you math chipmunks.
(kids cheer) - Next time, Math Park is being invaded by outer space aliens.
What do they want?
Find out next time.
