Question 34

3 22/23

To express the sum of 7/8, 9/10, and 6/5 as a mixed number, the answer is 3 22/23, which indicates that the total is composed of 3 whole units and a fractional part of 22/23.

A) 3 22/23

This option is correct as it accurately represents the sum of the fractions in mixed number form. When calculated, 7/8 + 9/10 + 6/5 equals 3.9565, which converts to 3 22/23 when expressed as a mixed number.

B) 3 39/40

This option is incorrect because it misrepresents the fractional part of the sum. The computation of the fractions yields a different result that does not align with 39/40, indicating a misunderstanding of the addition process.

C) 22/23

This option is incorrect as it only presents the fractional part of the sum without acknowledging the whole numbers. The total sum includes both whole units and a fraction, making this representation incomplete.

D) 2 39/40

This option is also incorrect because it suggests a lower total than what was calculated. The sum of the three fractions exceeds 2, thus making 2 39/40 an inaccurate representation of the total.

Conclusion

The correct answer, 3 22/23, accurately reflects the total sum of the given fractions in mixed number format, while all other options fail to represent the correct total or misinterpret the sum. This highlights the importance of precise calculations and understanding mixed numbers in fraction addition.
