Answer 2

120 gallons of gasoline needs 180 ounces of oil

Explanation:

Since the label for the chain saw reads to mix 3 ounces of oil with 5 gallons of gasoline, it means we have a ratio of 3 ounces of oil to 5 gallons of gasoline. That is

3 ounces of oil = 5 gallons of gasoline

Using the the unity method, by dividing both sides by 5,

3/5 ounces of oil = 1 gallon of gasoline.

So, for 120 gallons of gasoline, we have

120 × 1gallon of gasoline = 120 × 3/5 ounces of oil

So, 120 gallons of gasoline = 60 × 3 ounces of oil

So, 120 gallons of gasoline = 180 ounces of oil

So, 120 gallons of gasoline needs 180 ounces of oil
