Michaels car has a 18.0 gallon tank. If the tank has 5.5 gallons what fraction of the tank is full?

5.5/18 = 11/36

11/36

5.5/18 can't be simplified

To find the fraction of the tank that is full, we need to divide the current amount of fuel (5.5 gallons) by the total tank capacity (18.0 gallons).

The fraction can be calculated as follows:
Fraction = Current amount of fuel / Total tank capacity

Fraction = 5.5 gallons / 18.0 gallons

To simplify the fraction, we can divide both the numerator and the denominator by the greatest common divisor (GCD) of 5.5 and 18.0, which is 0.5.

5.5 gallons ÷ 0.5 = 11 gallons
18.0 gallons ÷ 0.5 = 36 gallons

Now we have:
Fraction = 11 gallons / 36 gallons

So, the fraction of the tank that is full is 11/36.
