To estimate the product of [tex]\(78.8 \times 6.8\)[/tex], we can round the numbers to more convenient values and then multiply those rounded values:
1. Rounding the numbers:
- [tex]\(78.8\)[/tex] rounds to [tex]\(80\)[/tex] (nearest ten).
- [tex]\(6.8\)[/tex] rounds to [tex]\(7\)[/tex] (nearest whole number).
2. Multiplying the rounded numbers:
[tex]\[
80 \times 7
\][/tex]
3. Calculate the estimated product:
[tex]\[
80 \times 7 = 560
\][/tex]
Therefore, the estimated product of [tex]\(78.8 \times 6.8\)[/tex] is [tex]\(560\)[/tex].
The correct answer is:
(B) 560
