Question

A scientist polls 40 people, asking if they would participate in a study. 55% say yes. How many people said yes

Answer 1

22 people

Explanation:

First, let's convert the percentage into a decimal so we can multiply the two.

55% = 0.55

Next, we'll multiply 40 times 0.55. This is so we can find the amount of people who said yes. (55% of people said yes.)

0.55*40 = 22

22 people said yes.
