what is the correct solution for this expression
2/5+3/8
To find the correct solution for the expression 2/5 + 3/8, you need to find a common denominator for both fractions and then add them together.
First, find the least common multiple (LCM) of 5 and 8, which is 40. Multiply the numerator and denominator of the first fraction, 2/5, by 8 to get:
(2 * 8) / (5 * 8) = 16/40
Next, multiply the numerator and denominator of the second fraction, 3/8, by 5:
(3 * 5) / (8 * 5) = 15/40
Now that both fractions have a common denominator of 40, you can add them together:
16/40 + 15/40 = 31/40
Therefore, the correct solution for the expression 2/5 + 3/8 is 31/40.
