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

\newline

12\frac{11}{16}

\,–\,

9\frac{7}{15}

\newline

The difference is approximately

\underline{\hspace{2em}}

Round to Nearest Whole Number: Step $1$ : Round $12 \frac{11}{16}$ to the nearest whole number. $\newline$ $12 \frac{11}{16}$ is closer to $13$ than to $12$ because $\frac{11}{16}$ is more than half. $\newline$ Rounded value = $13$
Subtract Rounded Values: Step $2$ : Round $9\frac{7}{15}$ to the nearest whole number. $\newline$ $9\frac{7}{15}$ is closer to $9$ than to $10$ because $\frac{7}{15}$ is less than half. $\newline$ Rounded value = $9$
Calculate Difference: Step $3$ : Subtract the rounded values. $\newline$ $13 - 9 = 4$ $\newline$ The difference is approximately $4$
