First, turn the mixed numbers into improper fractions by doing denominator times the whole number.
8 x 7 = 56 and 4 x 3 = 12
Second, add the numerator to the number you got above^
56 + 7 = 63 and 12 x 1 = 12
Third, turn it into a fraction.
63/8 and 12/4
Fourth, find the LCM which is 8.
That brings your fraction to 63/8 and 24/8
Fifth, simply subtract.
63/8 - 24/8 = 39/8
Finally, turn it back into a mixed number by seeing how many times does 8 go into 39.
That will make your answer 4 7/8
