Verified Answer :

The problem is \(21 \frac{11}{12} + 17 \frac{5}{12}\)

Add the whole numbers

\(21 + 17 = 38\)

Match up the fractions and make sure the denominators are the same (they are)

\(\frac{11}{12} + \frac{5}{12}\) \(= \frac{16}{12}\)

Break down the fraction 

\(16\) ÷ \(12 = 1 \frac{4}{12}\)

Reduce-You need to find a common factor for both the numerator and denominator

\(4\) ÷ \(4\) \(= 1\)

\(12\) ÷ \(4 = 3\)

Combine everything

\(38 + 1\frac{1}{3} =39 \frac{1}{3}\)

Answer: \(39 \frac{1}{3}\)
