Q. Estimate the difference. Round each number to the nearest whole number, then subtract.

\newline

10 \frac{13}{16}

-

8 \frac{11}{17}

\newline

The difference is approximately

\underline{\hspace{3em}}

Round to Nearest Whole Number: Step $1$ : Round $10\frac{13}{16}$ to the nearest whole number. $\newline$ $10\frac{13}{16}$ is closer to $11$ than to $10$ because $\frac{13}{16}$ is more than half. $\newline$ Rounded value = $11$
Subtract Rounded Values: Step $2$ : Round $8\frac{11}{17}$ to the nearest whole number. $\newline$ $8\frac{11}{17}$ is closer to $9$ than to $8$ , since $\frac{11}{17}$ is more than half. $\newline$ Rounded value = $9$
Calculate Estimated Difference: Step $3$ : Subtract the rounded values. $\newline$ $11 - 9 = 2$ $\newline$ The estimated difference is $2$ .
