Answer:
A) 15/4
Step-by-step 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:
[tex]\frac{5}{1}*\frac{3}{4}=\frac{15}{4}[/tex]
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.
