Question

11) To make the water safe for the fish, Logan has to put1/4 cup of solution for every gallon of water. If he uses 121/3 gallons of water, what is the total amount of solution heneeds to make the water safe for his fish?

Answer 1

EXPLANATION

Let's see the facts:

- (1/4) solution / gal water

-He uses: 12 1/3 gallon of water

In order to find the amount of solution he needs to make the water safe we must apply the unitary method as shown as follows:

`\text{Amount solution=}\frac{(1)/(4)\text{solution}}{\text{gal water}}\cdot12(1)/(3)\text{gal water=}(37)/(12)=3(1)/(12)\text{cups of solution}`

He should use 3 1/12 cups of solution to make the water safe
