Estimate the difference. Round each number to the nearest whole number, then subtract. 10 9/13 – 8 1/2 The difference is approximately _____.

Round to Nearest Whole Number: Step 1: Round 10 9/13 to the nearest whole number. 10 9/13 is closer to 11 than to 10 because 9/13 is more than half. Rounded value = 11 Subtract Rounded Values: Step 2: Round 8 1/2 to the nearest whole number. 8 1/2 is exactly between 8 and 9, but we round up when it's a half. Rounded value = 9 Step 3: Subtract the rounded values. 11 - 9 = 2 Difference = 2

The difference is approximately _____.

Round to Nearest Whole Number: Step $1$ : Round $10\frac{9}{13}$ to the nearest whole number. $\newline$ $10\frac{9}{13}$ is closer to $11$ than to $10$ because $\frac{9}{13}$ is more than half. $\newline$ Rounded value = $11$
Subtract Rounded Values: Step $2$ : Round $8\frac{1}{2}$ to the nearest whole number. $\newline$ $8\frac{1}{2}$ is exactly between $8$ and $9$ , but we round up when it's a half. $\newline$ Rounded value = $9$
Subtract Rounded Values: Step $2$ : Round $8 \frac{1}{2}$ to the nearest whole number. $\newline$ $8 \frac{1}{2}$ is exactly between $8$ and $9$ , but we round up when it's a half. $\newline$ Rounded value = $9$ Step $3$ : Subtract the rounded values. $\newline$ $11 - 9 = 2$ $\newline$ Difference = $2$
