Round to Nearest Whole Number: Step $1$ : Round $15 \frac{3}{4}$ to the nearest whole number. $\newline$ $15 \frac{3}{4}$ is closer to $16$ than it is to $15$ because $\frac{3}{4}$ is more than half. $\newline$ Rounded value = $16$
Subtract Rounded Values: Step $2$ : Round $15\frac{8}{19}$ to the nearest whole number. $\newline$ $15\frac{8}{19}$ is closer to $15$ than it is to $16$ because $\frac{8}{19}$ is less than half. $\newline$ Rounded value = $15$
Subtract Rounded Values: Step $2$ : Round $15\frac{8}{19}$ to the nearest whole number. $\newline$ $15\frac{8}{19}$ is closer to $15$ than it is to $16$ because $\frac{8}{19}$ is less than half. $\newline$ Rounded value = $15$ Step $3$ : Subtract the rounded values. $\newline$ $16 - 15 = 1$ $\newline$ Difference = $1$
