What is the top number called?

The numerator!

What is the bottom number

called? The

denominator!

Name the denominator

Name the denominator

in this fraction.

712 12!

Count the spaces between the WHOLE numbers on the number line.

0 1

1 2 3 4

Now add ONE to that number…

4 + 1 = 5

0 1

1 2 3 4

That is your denominator!

4 + 1 = 5

0 1

1 2 3 4

So now just starting counting by 1s, starting with 1. Your WHOLE number will have the same number as

the numerator and denominator.

What is the DENOMINATOR of your fraction?

0 1

Count the spaces between the WHOLE numbers on the number line and add 1!

So the denominator is 2 + 1 = 3!

What is the DENOMINATOR of your fraction?

First count the spaces in between, and then add 1!

0 1

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

So 15 + 1 = 16!Your denominator is 16!

It doesn’t matter if the WHOLE NUMBERS are 0 and 1….

They might be 2 & 3!

You still count the spaces and add 1…

(2 + 1 = 3 is the denominator!)

But you add the WHOLE NUMBER in front of the fractions!

You still count the spaces and add 1!
