Question

A landscaper can mow 3 acres in 2 hours at this rate how many acres can he mow in 1.5 hours

Answer 1

If you set up a proportion where acres are on top and time is on the bottom, you'll be able to cross multiply, similar to the picture, giving you the answer of 2.25 acres.

Answer 2

you must find half of three because 2 is half and 3 is how many ackers then 1.5÷1.5=0.75
I might be wrong but I believe that's the answer
