If it takes 13 machines 13 minutes to produce 13 widgets, how many minutes does it take 80 machines to produce 80 widgets?

Hello There!

Divide everything by 13 to get the unit rate:
It takes 1 machine 1 minute to produce 1 widget.
Therefore it takes 80 machines 80 minutes to produce 80 widgets.

Hope This Helps You!
Good Luck :)
