Question
Estimate the product. Round each factor to the nearest whole number, and then multiply.4.61 × 6.50
Solution
Step 1: Round each factor to the nearest whole number.
4.61 rounds to 5 because .61 is more than half way between 4 and 5. 6.50 rounds to 7 because .50 is exactly half way between 6 and 7, and we round up in this case.
Step 2: Multiply the rounded numbers.
5 × 7 = 35
So, the estimated product of 4.61 and 6.50, when each factor is rounded to the nearest whole number, is 35.
