Rationale

3 & 39/40 is the result of adding 7/8 + 9/10 + 6/5 as mixed numbers.

A (3 & 39/40) YOUR ANSWER

This option is actually the correct answer, derived from the proper addition of the fractions. It reflects the accurate sum of the mixed numbers resulting from the process of finding a common denominator and adding the fractions.

B (22/23) YOUR ANSWER

This choice represents a single fraction, which does not properly reflect the sum of the three mixed numbers provided in the question. The addition of the fractions yields a mixed number, not a simple fraction, making this option incorrect.

C (2 & 39/40) CORRECT

While this option shares the same fractional part as the correct answer, the whole number part is incorrect. The cumulative whole number from adding 7/8, 9/10, and 6/5 is 3, not 2, leading to this option being incorrect.

D (3 & 22/23) YOUR ANSWER

This choice has the correct whole number part but the fractional part is incorrect. The correct addition of the fractions results in 39/40, not 22/23, making this option invalid despite having the correct whole number.

Conclusion

The process of adding 7/8, 9/10, and 6/5 results in 3 & 39/40, showcasing the importance of correctly calculating and converting fractions to mixed numbers. The other options either misrepresent the whole number, the fractional part, or are incorrect altogether, reinforcing the necessity of careful arithmetic in fraction addition.
