Question

at one table, five people are sharing three-quarters of a pizza: what equal size portion of the pizza will each of the five people receive

Answer 1

In order to calculate the size portion that each of the five people will receive, we just need to divide the total amount of pizza (three-quarters = 3/4) by the amount of people (5), so we have:

$\frac{\frac{3}{4}}{5}=\frac{3}{4}\cdot\frac{1}{5}=\frac{3}{20}$

So each of the five people will receive 3/20 of the pizza.
