Step-by-step explanation:
To estimate the sum of the decimals by rounding to the nearest whole number, you need to round each decimal to the nearest whole number and then add them together.
For 5.493, rounding to the nearest whole number gives 5. For 6.009, rounding to the nearest whole number gives 6. And for 2.702, rounding to the nearest whole number gives 3.
Adding 5 + 6 + 3, the estimated sum of the decimals when rounded to the nearest whole number is 14.
