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

\newline

13\frac{2}{15}

–

10\frac{1}{18}

\newline

The difference is approximately _____.

Round to Nearest Whole Number: Step $1$ : Round $13\frac{2}{15}$ to the nearest whole number. $\newline$ $13\frac{2}{15}$ is approximately $13$ because $\frac{2}{15}$ is less than half, so we round down. $\newline$ Calculation: $13\frac{2}{15} \approx 13$
Subtract Rounded Numbers: Step $2$ : Round $10\frac{1}{18}$ to the nearest whole number. $\newline$ $10\frac{1}{18}$ is approximately $10$ because $\frac{1}{18}$ is less than half, so we round down. $\newline$ Calculation: $10\frac{1}{18} \approx 10$
Subtract Rounded Numbers: Step $2$ : Round $10 \frac{1}{18}$ to the nearest whole number. $\newline$ $10 \frac{1}{18}$ is approximately $10$ because $\frac{1}{18}$ is less than half, so we round down. $\newline$ Calculation: $10 \frac{1}{18} \approx 10$ Step $3$ : Subtract the rounded numbers. $\newline$ $13 - 10 = 3$ $\newline$ Calculation: $13 - 10 = 3$
