Jayce sold 218 cups of lemonsde at his limonate stand. what is 218 rounded to the nearest ten

The answer would be 220, because you would look at the 8, and the 8 determines what your number would be in your tenths place, and 8 is bigger than 5, so you would round to 220

218, look and the tens place, the tens place is a 1. now look at the right of the tens place. the rule is if the right digit of the place value your rounding is 5 or above, round up, if it's 4 or below, round down.

clearly 8 is 5 or above, so we round up. 218 rounded to the nearest ten is 220.
