RRB NTPC 2024 Undergraduate CBT 1 Question Paper (29-Aug-2025) (Shift 1)
The correct answer is

\(\frac{19}{24}\)

To add the fractions \(\frac{3}{8}\) and \(\frac{5}{12}\), we first need to find a common denominator. The least common multiple (LCM) of 8 and 12 is 24. We then rewrite each fraction with the common denominator of 24:

\(\frac{3}{8} = \frac{3 \times 3}{8 \times 3} = \frac{9}{24}\)

\(\frac{5}{12} = \frac{5 \times 2}{12 \times 2} = \frac{10}{24}\)

Now we can add the fractions:

\(\frac{9}{24} + \frac{10}{24} = \frac{9 + 10}{24} = \frac{19}{24}\)

Therefore, the sum of \(\frac{3}{8}\) and \(\frac{5}{12}\) is \(\frac{19}{24}\).
