$3 \frac{17}{22} + 1 \frac{53}{56}$
the sum is approximately \boxed{}.

Explanation:

Step1: Round \(3\frac{17}{22}\) to nearest whole number

The fraction \(\frac{17}{22}\approx0.77\), which is more than \(0.5\), so \(3\frac{17}{22}\approx4\)

Step2: Round \(1\frac{53}{56}\) to nearest whole number

The fraction \(\frac{53}{56}\approx0.95\), which is more than \(0.5\), so \(1\frac{53}{56}\approx2\)
