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

If the mixture requires 5 gallons of gas for every 2 gallons of oil, then the ratio of gas to oil is 5:2.

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