Andy is mowing grass. The mixture requires 5 gallons of gas for every 2 gallons of oil. How much oil is needed for 8 gallons of gas? Answer should be in tenths

Answer 1

To find out how much oil is needed for 8 gallons of gas, we can set up a proportion based on the given ratio.

We know that 5 gallons of gas require 2 gallons of oil.

So, for every 5 gallons of gas, there are 2 gallons of oil.

And for every 1 gallon of gas, there are 2/5 gallons of oil.

Now, let's find out how much oil is needed for 8 gallons of gas:

8 gallons of gas = 8 * (2/5) gallons of oil
= 16/5 gallons of oil

Converting this fraction into tenths:

16/5 = 3.2

Therefore, 8 gallons of gas requires 3.2 gallons of oil.
