Question

A solution must be 14% insecticide. To make 3/4 gallon of this solution,how much insecticide must you use?

Answer 1

We require 0.105 gallons of insecticide to make
`\displaystyle(3)/(4)\text{ gallons}` of the solution.

Explanation:

We are given the following information in the question:

A solution must be 14% insecticide.

Amount of solution to be made =

`\displaystyle(3)/(4)\text{ gallons}`

Amount of insecticide to be used =

`14\%* \text{Solution to be made} = 14\%* \displaystyle(3)/(4)\\\\= \displaystyle(14)/(100)* (3)/(4)\\\\= (21)/(200)\text{ gallons} = 0.105\text{ gallons}`

Thus, we require 0.105 gallons of insecticide to make
`\displaystyle(3)/(4)\text{ gallons}` of the solution.
