Question

A motorist is pumping gas into his car at a rate of 5/12 of a gallon every 1/24 of a minute. At this rate, how many gallons of gas will he have pumped into his car in 1/2 of a minute?

Answer 1

the answer is b which is 5

Answer 2

Well 1/2=12/24 so we just need to do 5/12*12, so you would get 5 gallons as the 12 would cancel each other out leaving you with 5.
