Question

A machine in a factory makes 2 1/4 pounds of nails in 1 1/2 hours. At what rate, in

pounds per hour, does the machine make nails?

Answer 1

the machine makes nails at a rate of 1.5 (1 1/2) pounds per hour

Explanation:

to figure out the rate in pounds per hour, you divide 2 1/4 (2.25) by three because 3 half hours = one and a half hours, which is where 2.25 pounds have been made. you end up with 0.75, but that only covers one half hour, so to figure out one hour, you add another 0.75 to 0.75 and end up with one and a half !!
