If an engine requires 20 ounces of oil for five gallons of gas, how much oil would be needed for eight gallons of gas?

... that's not how engines work.
An engine needs oil to keep its moving parts moving smoothly. The oil doesn't interact with the gasoline, and it doesn't get used up.
(Well, the oil gets used up very slowly as it evaporates or otherwise escapes from the engine. But it doesn't get deliberately burned like gasoline. You can refill your gas tank dozens of times before needing an oil change.)
The amount of oil required is based on the size of the engine and its parts. If a particular engine requires 20 ounces of oil then it ALWAYS requires 20 ounces of oil.

8 gallons/ 5 gallons x 20 oz = 32 ounces Answer//

8 gallons is your 'given', start there and apply converters = (1)
8 gal gas (20 floz Oil/5 gal gas) = 32 floz of oil
The units tell you how to work the problem mathematically.
((fyi, liquids are measured in floz, fluid ounces. Just 'oz' = weight))

Oil needed: 8/5 times 20 = 32 ounces

You need to figure out how many ounces of oil one gallon of gas needs; then you can multiply that by 8 (gallons). You'll find that if 5 gallons of gas get a total of 20 ouncea of oil mixed in, then each gallon is getting 4 ounces of oil. (20 divided by 5 = 4). So, 8 gallons (of gas) multiplied by 4 ounces (of oil), equals 32 ounces of oil (8 x 4 = 32).
You'll need to have 32 ounces of oil on hand if you're using 8 gallons of gas.

There is 4 ounces of oil for 1 gallon of gas, so there are 32 ounces of oil for 8 gallons of gas or 1 quart of oil.

If we take the number of gallons of gas (5) and multiply it by 4, we get the number of ounces of oil (20).
So if we had 8 gallons of gas, we should have 32 ounces of oil.

x / 20 = 8 / 5
x = 20 * (8/5)
x = 160 / 5
x = 32

8/5 of 20 oz, which is 32 oz
