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:

5 gallons of gas = 2 gallons of oil
8 gallons of gas = x gallons of oil

Cross-multiplying, we get:
5 * x = 8 * 2
5x = 16

Dividing both sides by 5, we get:
x = 16/5

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