a) To estimate the value of 28.76 + 12.89, we can round each number to the nearest whole number. So, 28.76 rounds to 29 and 12.89 rounds to 13. Adding these together gives us an estimated sum of 42.

b) To estimate the value of 5.32 × 2.45, we can also round each number to the nearest whole number. So, 5.32 rounds to 5 and 2.45 rounds to 2. Multiplying these together gives us an estimated product of 10.
