Question 40

1 & 3/4

To solve the subtraction problem 2 5/8 - 7/8, we first convert 2 5/8 to an improper fraction, which is 21/8. Then, subtracting 7/8 from 21/8 gives us 14/8. Reducing 14/8 results in 1 & 3/4.

A) 1 & 5/8

Option A is incorrect because it does not reflect the correct result of the subtraction. The calculation shows that the difference is greater than 1 & 5/8.

B) 1 & 1/4

Option B is also incorrect. The result of the subtraction is higher than 1 & 1/4, indicating that this option does not accurately represent the answer.

C) 1 & 6/8

Option C is misleading as it represents an improper reduction of the fraction. While 1 & 6/8 simplifies to 1 & 3/4, the direct calculation shows that this is not the correct representation of the answer prior to reduction.

D) 1 & 3/4

Option D is correct. The proper calculation of 2 5/8 - 7/8 yields 14/8, which simplifies to 1 & 3/4, confirming that this is indeed the right answer.

Conclusion

The correct answer is 1 & 3/4, as it accurately reflects the result of the subtraction and is the final reduced form of the calculated difference. All other options fail to match the correct outcome, either by being lower than the result or misrepresenting the fraction after reduction.
