Question
Estimate the product. Round each factor to the nearest whole number, and then multiply.6.98 × 3.92
Solution
Step 1: Round each factor to the nearest whole number.
6.98 rounds up to 7 because .98 is closer to 1 than it is to 0.
3.92 rounds down to 4 because .92 is closer to 1 than it is to 0, but since we are rounding to whole numbers, we round down to 4.
Step 2: Multiply the rounded numbers.
7 (rounded from 6.98) multiplied by 4 (rounded from 3.92) equals 28.
So, the estimated product of 6.98 and 3.92, when each factor is rounded to the nearest whole number, is 28.
