Question

1,500 people tried a cream. Nine people had a reaction. What percent of people had a reaction?

Answer 1

Answer:

0.006% of people had a reaction

Step-by-step explanation:

1,500 tried it -----> 9 had a reaction

9/1,500

Divide both numerator and denominator by 3

3/500

Multiply by 2 to get the fraction out of 1000

6/1000

Divide by 10 to get the fraction out of 100

0.6/100

0.006%
