Estimate the difference. Round each number to the nearest whole number, then subtract. 13 2/15 – 10 1/18 The difference is approximately _____.

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

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: $13 - 10 = 3$
