Answer

\frac{16}{21} Explanation 1. Identify Common Denominator Both fractions have the same denominator, 21, so we can directly add the numerators. 2. Add the Numerators Add the numerators: 11 + 5 = 16. The sum of the fractions is \frac{16}{21}. 3. Simplify the Fraction Check if \frac{16}{21} can be simplified. The greatest common divisor of 16 and 21 is 1, so the fraction is already in simplest form.
