Answer 1

The answer to this question is B. 16/40

Answer 2

B

Explanation:

To add 2/5 and 3/8, we need to find a common denominator for the two fractions.

The smallest multiple of 5 and 8 is 40, so we can use 40 as the common denominator.

Multiplying the numerator and denominator of 2/5 by 8, we get:

2/5 = 16/40

Multiplying the numerator and denominator of 3/8 by 5, we get:

3/8 = 15/40

Now, we can add the two fractions:

2/5 + 3/8 = 16/40 + 15/40

Simplifying the numerator, we get:

2/5 + 3/8 = 31/40

Therefore, 2/5 + 3/8 is equal to 31/40.
