Question 8

2 & 39/40

To express the sum of 7/8, 9/10, and 6/5 as a mixed number, the total simplifies to 2 & 39/40. This calculation involves finding a common denominator and summing the fractions accurately.

A) 3 & 39/40

This option is incorrect as it suggests a total greater than the actual sum of 7/8, 9/10, and 6/5. The correct sum does not exceed 3, making this option invalid.

B) 22/23

Option B is incorrect because it presents an improper fraction that does not represent the sum of the given fractions. The total calculated is a mixed number, not a simple fraction like 22/23.

C) 2 & 39/40

This option is correct as the sum of the fractions, when calculated and converted into a mixed number, equals 2 & 39/40. This accurately reflects the total after finding a common denominator and adding the fractions.

D) 3 & 22/23

This option is incorrect because it also exceeds the actual sum derived from the fractions. The total should be less than 3, hence this option does not accurately represent the addition of the given fractions.

Conclusion

The correct answer, 2 & 39/40, accurately reflects the sum of the fractions provided in the question. All other options either misrepresent the value by being too high or incorrectly formatted as simple fractions, failing to match the correct calculation.
