Randy needs to mow lawn. The mixture requires 5 gallons of gas for 2 gallons of oil. How much oil will she need for 8 gallons of gas your answer should be in tenths
To find out how much oil Randy will need for 8 gallons of gas, we need to set up a proportion based on the given ratio of 5 gallons of gas to 2 gallons of oil.
Let's represent the amount of oil Randy will need as "x".
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Cross multiply: 5 * x = 2 * 8
5x = 16
Divide both sides by 5: x = 16/5
In tenths, x = 3.2
Therefore, Randy will need 3.2 gallons of oil for 8 gallons of gas.
