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

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:

$0.05 \cdot 10 = 0.5 = \frac{1}{2}$ gallons of active ingredients.
