Full solution

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

\newline

6 \frac{19}{20}

-

6 \frac{2}{15}

\newline

The difference is approximately

\underline{\hspace{3em}}

.

Round Numbers: Step $1$ : Round each number to the nearest whole number. $\newline$ First, round $6\frac{19}{20}$ . Since $\frac{19}{20}$ is very close to $1$ , we round $6\frac{19}{20}$ up to $7$ . $\newline$ Next, round $6\frac{2}{15}$ . Since $\frac{2}{15}$ is much closer to $0$ than to $1$ , we round $6\frac{2}{15}$ down to $\frac{19}{20}$ $0$ .
Subtract Rounded Numbers: Step $2$ : Subtract the rounded numbers. $\newline$ Subtract the rounded values: $7 - 6 = 1$ .
