A company that makes hair-care products
had 3,000 people try a new shampoo. Of the
3,000 people, 9 had a mild allergic reaction.
What percent of the people had a mild
allergic reaction?

Respuesta :

Answer:

.3%

Step-by-step explanation:

9/3000x 100% = 0.3%

We divide 9/3000, multiply result by 100.

If we had 20 from 500 people who were sick, we do 20/500*100= 4 %
