Question 10

1 & 3/4

Subtracting 2 5/8 and 7/8 results in 1 & 3/4 when simplified correctly.

A) 1 & 5/8

This option is incorrect because it does not accurately represent the result of the subtraction. The calculation of 2 5/8 - 7/8 yields a larger value than 1 & 5/8.

B) 1 & 1/4

This option is also incorrect as it underestimates the result of the subtraction. The value of 1 & 1/4 does not align with the correct calculation of 2 5/8 - 7/8, which is greater.

C) 1 & 6/8

This choice is incorrect as it suggests a value that is not in its simplest form. While it may initially appear close, 1 & 6/8 simplifies to 1 & 3/4, which is not reflected in this option.

D) 1 & 3/4

This is the correct answer because it accurately reflects the simplified result of the subtraction. When performing the calculation, 2 5/8 - 7/8 equals 1 & 3/4.

Conclusion

The correct answer, 1 & 3/4, is reached through proper subtraction and simplification of the fractions involved. Other options either misrepresent the result or fail to simplify correctly, making them inaccurate responses to the question.
