Round to Nearest Whole Number: Step $1$ : Round $13 \frac{2}{3}$ to the nearest whole number. $\newline$ $13 \frac{2}{3}$ is closer to $14$ than it is to $13$ because $\frac{2}{3}$ is more than half. $\newline$ Rounded value = $14$
Subtract Rounded Values: Step $2$ : Round $10\frac{2}{5}$ to the nearest whole number. $\newline$ $10\frac{2}{5}$ is closer to $10$ than it is to $11$ because $\frac{2}{5}$ is less than half. $\newline$ Rounded value = $10$
Calculate Difference: Step $3$ : Subtract the rounded values. $\newline$ $14 - 10 = 4$ $\newline$ The difference is approximately $4$
