What is a Fraction?
A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given that the rate of water is 3/4 of a gallon in 1/5 of a minute. Therefore, the rate of water filling is,
Rate = (3/4) gallon / (1/5) minute
= (3×5)/(1×4) gallons per minute
= 15/4 gallons per minute
Since Don Calculated the unit rate to be 3/20 of a gallon per minute. Therefore, Don is wrong he had multiplied the fraction instead of dividing them.
