To find the sum of \( \frac{3}{8} \) and \( \frac{2}{5} \), we need to find a common denominator. The least common multiple of 8 and 5 is 40.
Now we can convert each fraction:
-
Convert \( \frac{3}{8} \) to a fraction with a denominator of 40: \[ \frac{3}{8} = \frac{3 \times 5}{8 \times 5} = \frac{15}{40} \]
-
Convert \( \frac{2}{5} \) to a fraction with a denominator of 40: \[ \frac{2}{5} = \frac{2 \times 8}{5 \times 8} = \frac{16}{40} \]
Now, we can add the two fractions: \[ \frac{15}{40} + \frac{16}{40} = \frac{15 + 16}{40} = \frac{31}{40} \]
Thus, the sum of \( \frac{3}{8} \) and \( \frac{2}{5} \) is \( \frac{31}{40} \).
The correct response is:
31/40
31 over 40
