Question

Jake and 4 friends each ate three-quarters of a pizza, how many pizzas did they consume all together?

A) 15/4
B) 19/5
C) 4/15
D) 7/2

Answer 1

A) 15/4

Explanation:

The problem states that Jake and his 4 friends were eating pizza, this would be a total of 5 people, including Jake. So, when you calculate the amount of pizza eaten, you will need to multiply by 5 people. Since each person ate three-quarters (3/4) of a pizza, you need to multiply:

`(5)/(1)*(3)/(4)=(15)/(4)`

When we multiply a whole number by a fraction, we place it over a denominator of 1. When multiplying fractions, we multiply the numerators together and the denominators together. So, the final answer is 15/4.
