2/5+5/8

Answer

To add 2/5 and 5/8, we need to find a common denominator and then add the fractions.

The least common denominator (LCD) of 5 and 8 is 40.

Now, let's rewrite the fractions with the LCD: 2/5 = (2/5)(8/8) = 16/40 5/8 = (5/8)(5/5) = 25/40

Now, we can add the fractions: 16/40 + 25/40 = (16 + 25)/40 = 41/40

Therefore, 2/5 + 5/8 = 41/40.
