3/4 + 1/8 + 7/20 =

Rationale

3/4 + 1/8 + 7/20 equals 19/40.

To find the sum of the fractions 3/4, 1/8, and 7/20, we first convert them to a common denominator, which is 40. The equivalent fractions are 30/40 (for 3/4), 5/40 (for 1/8), and 14/40 (for 7/20). Adding these gives us 30/40 + 5/40 + 14/40 = 49/40, which simplifies to 1{9/40}. Since this is not one of the provided answer choices, "None of the Above" is the correct answer.

A (1{9/40}) YOUR ANSWER

This choice reflects the simplified form of the sum, which equals 49/40 or 1{9/40}. However, it is not listed as one of the options in the question, making it an incorrect choice.

B ({11/32}) YOUR ANSWER

This fraction does not correspond to the sum of the given fractions. When calculated, 11/32 is approximately 0.34375, which is far less than the actual sum of 49/40 (or 1.225). Thus, this option is incorrect.

C (14/28) YOUR ANSWER

This fraction simplifies to 1/2, which is not related to the sum of the fractions provided. The result of 1/2 does not match the computed total of 49/40, making this choice incorrect.

D (19/20) YOUR ANSWER

This fraction equals 0.95, which is also not the sum of 3/4, 1/8, and 7/20. The correct sum exceeds 1, thus ruling out this option as well.

Conclusion

After calculating the sum of the fractions, we find the total is 49/40 or 1{9/40}, which is not listed among the provided answer choices. Therefore, the appropriate selection is "None of the Above," highlighting the importance of verifying calculations against available options.
