Q. Estimate the sum. Round each number to the nearest whole number, then add.

\newline

3\frac{1}{7}

+

1\frac{17}{18}

\newline

The sum is approximately _____.

Round to Nearest Whole Number: Step $1$ : Round $3 \frac{1}{7}$ to the nearest whole number. $\newline$ $3 \frac{1}{7}$ is approximately $3$ because $\frac{1}{7}$ is less than half. $\newline$ Calculation: $3 \frac{1}{7} \approx 3$
Add Rounded Numbers: Step $2$ : Round $1\frac{17}{18}$ to the nearest whole number. $\newline$ $1\frac{17}{18}$ is approximately $2$ because $\frac{17}{18}$ is very close to $1$ . $\newline$ Calculation: $1\frac{17}{18} \approx 2$
Add Rounded Numbers: Step $2$ : Round $1\frac{17}{18}$ to the nearest whole number. $\newline$ $1\frac{17}{18}$ is approximately $2$ because $\frac{17}{18}$ is very close to $1$ . $\newline$ Calculation: $1\frac{17}{18} \approx 2$ Step $3$ : Add the rounded numbers. $\newline$ $3 + 2 = 5$ $\newline$ Calculation: $3 + 2 = 5$
