Question

A certain bleach is 5% active ingredients. In 10 gallons of this bleach, how much is active ingredients?

Answer 1

I got `0.5` gallons.

Explanation:

We have that `5%` correspnds to:

`(5%)/(100%)=0.05` of a certain amount

so in case of `10` gallons we get:

`0.05*10=0.5=1/2` gallons of active ingredients.
