multiply the number in front of the fraction on the mixed number by the denominator and add that to the numerator to convert it to an improper fraction, then add
For example:
If you want to subtract 3/4 from 10 2/3, you have to first convert the 10 2/3 to an improper fraction, which would be 32/3. Next you have to find the common denominator for both fractions. 3 x 4 = 12, so 12 is the lowest common denominator; therefore, 3/4 = 9/12 and 32/3 = 128/12.
Now you can perform the operation:
128/12 - 9/12 = 117/12; convert 117/12 to a mixed number by dividing 117 by 12, which is 9 with a remainder of 9; 117/12 becomes 9 9/12 or 9 3/4.
