Find the difference in 7 7/8 - 3 1/4

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
