Question 38

4 & 1/5

The result of subtracting 12 by 7 and 4/5 is 4 and 1/5. This calculation shows how to effectively handle mixed numbers in subtraction.

A) 5 & 1/5

This option is incorrect because it represents a value that is greater than the actual result. The calculation of 12 - 7 and 4/5 yields a smaller number than 5 and 1/5.

B) 4 & 4/5

This choice is also incorrect as it suggests a value that is too high. The correct subtraction of 12 minus 7 and 4/5 results in a value that does not reach 4 and 4/5.

C) 5 & 4/5

Option C is incorrect because it implies an even larger value than the correct answer. The result of the subtraction does not approach 5 and 4/5.

D) 4 & 1/5

This is the correct answer. When performing the subtraction, 12 - 7 and 4/5 equals 4 and 1/5, accurately reflecting the decrease in value.

Conclusion

The correct answer is definitively 4 and 1/5, as it directly results from the proper subtraction of 12 and 7 and 4/5. All other options fail to represent the correct value, demonstrating a misunderstanding of mixed number arithmetic.
