Angie can peel 1/6 of a crate of potatoes every 1/18 of a hour. complete the unit rate.
To find the unit rate, we need to divide the amount of potatoes peeled by the time taken.
So, the unit rate is:
1/6 crate of potatoes per 1/18 hour = (1/6) / (1/18) = (1/6) * (18/1) = 3 crates of potatoes per hour.
Therefore, the unit rate is 3 crates of potatoes per hour.
