__Parts of a fractions and adding fractions with like denominators__ 

The numerator is the top part of the Fraction: 4

 The denominator is the bottom part of the Fraction: 15

It can also be written as 4/15

Adding Fractions is done when the denominators are the same,

1.) Add the numerators !!!

2.) Keep the same number as the denominator

How about an example

5/9 + 2/9 = ???????

Denominators the same so add the numerators and keep the same DENOMINATOR !!!!!!

5/9 + 2/9 = 7/9

Numerator = 5 +2 = 7

Don't touch that denominator = 9
