What are Fractions?

**Fractions **describe a part of a whole.

Let's say you have one **whole **chocolate. π

You want to share it with your best friend. π€

So you split the chocolate into **two equal parts**.

Now you have **2 pieces **of chocolate.

Each piece has the **same size**.

π You can say that each piece is **1 out of 2 equal parts **of the **whole **chocolate.

β
You can say that each piece is **1/2, or one half, of the whole **chocolate.

**1/2** is a fraction. We read it as "**one half**".

πEvery time you divide a whole into several equal parts, you get a fraction!

β
If you cut a pizza into **4 equal slices**, then each slice is **1 out of 4 equal parts **of the whole pizza.

You can say that each slice is **1/4 of the whole pizza**!Β

**1/4 **is read out loud as "**one fourth**".

β
If you cut a rope into **3 pieces of equal length**, then each piece is **1 out of 3 equal parts **of the whole rope.

You can say each piece is **1/3 of the whole rope**!

**π 1/2,** **1/4,** and **1/3 **are all examples of fractions.

There are 2 parts to a fraction: the **numerator **and the **denominator**.

Do you remember what they mean?

That's right!

The **numerator **is the number **above **the fraction bar. π

The **denominator **is the number **below **the fraction bar. π

The **numerator **describes the number of parts you have.

The **denominator **describes how many equal parts the whole is divided into.

When you say **1/2**, that means the whole is divided into 2 equal parts and you have **1 out of the 2 parts**.

When you say **1/4**, that means the whole is divided into 4 equal parts and you have **1 out of the 4 parts**.

What happens if you have **more than 1 part of the whole**? π€

You write the number of parts **you have **in the** numerator**! π

Let's say you have a whole pizza and cut it into 4 equal slices.

Your brother ate **2 slices **of the pizza.

What fraction of the whole pizza did your brother eat? π

That's right!

He ate **2 out of the 4 equal parts **of the whole pizza.

This means he ate **2/4 of the whole **pizza!

π Did you see how we wrote the number of parts he ate in the numerator?

**π€ Tip: **Whenever you have more than 1 part of the whole, write the number of parts you have in the **numerator.** That's the number you write at the top of the fraction bar.

Now that you know fractions, let's write the word form of some fractions.

π To write fractions in word form, spell the numbers out and place a dash between the two words.

**1/2** is **one-half**

**1/3** is **one-third**

**1/4 **is **one-fourth**

**2/5 **is **two-fifths**

**3/6 **is **three-sixths**

**4/7 **is **four-sevenths**

**5/8 **is **five-eighths**

**6/9** is **six-ninths**

**7/10 **is **seven-tenths**

**Tip: **The denominator when written in words is usually an ordinal number.
