Jamaal ate 1 and 1/2 of a pizza. eric ate 7/8 of a pizza. how much pizza did jamaal and eric eat in all ?

Before you can add these fractions, you first need to make a common denominator. The GCF of 2 and 8 is 8, so you need to make 1/2 into a fraction with 8 as the denominator. 1/2 is equal to 4/8. 

Add the fractions together. 

1 4/8 + 7/8 = 2 3/8

Your answer should be:

2 3/8

5\16 x 2\5 = 10/80simplify to 1/80
