Question

For every gallon of water in a swimming pool, you’ Instructed to add four grams of chlorine. How many grams of chlorine would you add to a pool containing 13 gallons of water?

Answer 1

52 grams

Explanation:

This problem can be solved simply by applying the ratio method.

We know that 1 gallon of waters requires 4 grams of Chlorine in the swimming pool, so we can assume the number of grams of Chlorine required for 13 gallons of water to be x.

So we can write it as:

`(1 gallon of water)/(13 gallons of water) = (4g of Chlorine)/(x)`

So x will be equal to
`= 13 * 4 = 52`

Therefore, 52 grams of Chlorine is required for 13 gallons of water in the swimming pool.

Answer 2

52

Explanation:

Multiply grams per gallon times gallons to get grams.

`4\,(g)/(gal)* 13\,gal=4* 13\,(g\cdot gal)/(gal)=52\,g`
