he would need 14 fluid ounces of concentrated soap.

Step-by-step explanation:

The directions call for 4 fluid ounces of concentrated soap for every 3 cups of water.

1 cup = 8 fluid ounces

Converting 3 cups of water to fluid ounces, it becomes

3 cups = 3 × 8 = 24 fluid ounces

Kevin uses 84 fluid ounces of water to make an all-purpose cleaner. This means that the amount of concentrated soap that he would use is

(84 × 4)/24 = 336/24 = 14 fluid ounces of concentrated soap
