Randi needs to mow her lawn. The mixture requires 5 gallons of gas for every 2 gallons of oil. How much oil will she need for 8 gallons of gas? Your answer should be in tenths. (1 point)

Answer 1

To find out how much oil Randi will need for 8 gallons of gas, we can set up a proportion.

If 5 gallons of gas requires 2 gallons of oil, then 8 gallons of gas will require x amount of oil.

Using cross products, we get:

5/2 = 8/x

Cross-multiplying, we get:

5x = 2 * 8

5x = 16

Dividing both sides by 5, we get:

x = 16/5 = 3.2

Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
