Answer 1

Mika estimated the sum to be 216. The actual sum is 216.

Step-by-step explanation:

Mika estimated the sum of 189.27, 15.8, and 11.2 by rounding each number to the nearest whole.

To estimate the sum, we round each number to the nearest whole number: 189.27 becomes 189, 15.8 becomes 16, and 11.2 becomes 11. The estimated sum is 189 + 16 + 11 = 216.

The actual sum of the numbers is 189.27 + 15.8 + 11.2 = 216.27. So, Mika's estimate and the actual sum are both 216.
