Question

Rebecca asked the people in her homeroom class what their favorite type of pizza was. If 18

out of 25 people said pepperoni, how many people would you expect to choose pepperoni
out of 350 people?

Answer 1

x = people who chose pepperoni = 252

Explanation:

Number of people : people who chose pepperoni = 25 : 18

how many people would you expect to choose pepperoni

out of 350 people?

Let x = people who chose pepperoni

Number of people : people who chose pepperoni = 350 : x

Equate both ratios

25 : 18 = 350 : x

25/18 = 350/x

Cross product

25*x = 18*350

25x = 6,300

x = 6,300/25

x = 252

x = people who chose pepperoni = 252
