Question

Kevin uses 84 fluid ounces of water to make an all-purpose cleaner. The directions call for 4 fluid ounces of concentrated soap for every 3 cups of water. How many fluid ounces of soap should he use

Answer 1

Answer:

886 fluid ounces.

Step-by-step explanation:

Know that 8 fluid ounces makes 1 cup.

Now 24 cups need 32 fluid ounces

or, 3 fluid ounces of water need 32 fluid ounces of soap.

Thus, by unitary method,

84 ounces of water need 32×84/3 ounces of soap.

Thus the answer comes to 886 ounces.

Answer 2

He should use 14 fluid ounces of soap.

Step-by-step explanation:

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

Since, 1 cup = 8 fluid ounces

Kevin uses the amount of water = 84 fluid ounces.

84 fluid ounces = 84/8 =  10.5 cups

Hence, Kevin uses 10.5 cups of water.

∵ for 3 cups of water, the quantity of soap is used = 4 fluid ounces

∴ for 1 cups of water, the quantity of soap is used = $\frac{4}{3}$

∴ for 10.5 cups of water, the quantity of soap is used = $\frac{4}{3}\times 10.5$

                                                                                        = 14 fluid ounces

He should use 14 fluid ounces of soap.
