Q. Estimate the sum. Round each number to the nearest whole number, then add.

\newline

8\frac{1}{4}

+

1\frac{16}{17}

\newline

The sum is approximately _____.

Round Numbers: Step $1$ : Round each number to the nearest whole number. $\newline$ $8 \frac{1}{4}$ rounds to $8$ because $\frac{1}{4}$ is less than half. $\newline$ $1 \frac{16}{17}$ rounds to $2$ because $\frac{16}{17}$ is very close to $1$ , making it round up.
Add Rounded Numbers: Step $2$ : Add the rounded numbers. $8$ (rounded from $8 \frac{1}{4}$ ) + $2$ (rounded from $1 \frac{16}{17}$ ) = $10$ .
