Answer:
Part 1: 4 times heavy
Part 2: 2 times heavy
Step-by-step explanation:
Part 1:
We need to divide the weight of extra large by weight of small to get our answer.
Let's first convert to improper fraction:
6 1/2 = 13/2
1 5/8 = 13/8
Now,
[tex]\frac{\frac{13}{2}}{\frac{13}{8}}=\frac{13}{2}*\frac{8}{13}=4[/tex]
extra large pizza is 4 times as heavy as small pizza
Part 2:
Similar to part 1. Let's convert medium to improper fraction:
3 1/4 = 13/4
Now,
[tex]\frac{\frac{13}{4}}{\frac{13}{8}}=\frac{13}{4}*\frac{8}{13}\\=2[/tex]
Medium pizza is 2 times heavier than small pizza
