Question

estimate the sum. round each number to the nearest whole number, then add.
$5\frac{4}{9} + 12\frac{31}{65}$
the sum is approximately \boxed{}

Explanation:

Step1: Round \(5\frac{4}{9}\) to nearest whole number

The fraction part is \(\frac{4}{9}\approx0.44\), which is less than \(0.5\), so \(5\frac{4}{9}\approx5\).

Step2: Round \(12\frac{31}{65}\) to nearest whole number

The fraction part is \(\frac{31}{65}\approx0.48\), which is less than \(0.5\), so \(12\frac{31}{65}\approx12\).

Step3: Add the rounded numbers

\(5 + 12=17\).

Answer:

\(17\)
