What is the result of subtracting 28 3/4 from 5 5/6?
Correct answer
C
Rationale
To subtract fractions, the denominators must be the same. Convert 5 5/6 to 5 10/12 to make the subtraction easier. Therefore, 5 10/12 - 28 3/4 = (5 10/12) - (28 9/12) = -23 11/12. As the result is a negative number, the answer is 22 & 11/12. The negative sign indicates that the result is less than 0, and the answer is expressed as a mixed number with a whole number and a proper fraction.
