Question

Mary Jane has 3/8 of a medium pizza left.hector has 2/8 of another medium pizza left how much pizza do they Have altogether? Use models to hlp

Answer 1

let the total size of Pizza that they both have be given by P. 
P=(size of Mary Jane left over)+(size of Hector leftover)
size of Mary Jane left over=3/8
size of Hector leftover=2/8
hence the total will be:
P=3/8+2/8
P=(3+2)/8
P=5/8
therefore the fraction of remaining pizza that was left by both was 5/8

Answer 2

The 2 pizzas are the same size (medium), so we only need to add the fractions: 3/8 + 2/8 = (3+2)/8 = 5/8, or, there is a total of 5/8 of a medium pizza remaining.
