Answer: Dante slices 8.5 potatoes per minute.
Explanation: To find the unit rate look at the steps below.
102:12
12/12 gives us 1 minute and 102/12 gives us 8.5 We divide both numbers by 12 because if we divide 12 by 12 we get one minute and when we divide the other side it tells us how many potatoes Dante slices in one minute.
