Demont used 4 gallons of gasoline in three days driving to to work. each day he used the same amount of gasoline. hkw many gallons of gasoline did he use each day?

The answer is 1.3 gallons per day.

He uses 4 gallons for 3 days. We need to find a number of gallons (x) per 1 day.

Make a proportion:

4 gallons : 3 days = x : 1 day

x = 4 gallons * 1 day : 3 days

x = 4/3 gallons

x = 1.3 gallons
