Question

Katy was picking berries. She picked 135 berries in 15 minutes. If she continues picking at that rate, how many total berries will she pick in 25 minutes?

Answer 1

She will pick 486 berries in 25 minutes.

Answer 2

Okay, so how to explain the problem is that you have to make 135/15 into a unit rate, by doing 135 divided by 15 to equal 9/1, and then you multiply that by 25, and you got your answer, which is 225/25. The 9/1 means 9 berries per 1 minute. The other person got a different answer, but I think this is the correct way to do it, unless I am wrong.
