It's basic subtraction. you subtract 7 1/8 with 4 4/8 by turning one of the one from the seven to 8/8 and add that to 1/8 so you get 9/8. Then 6 9/8 - 4 4/8 = 2 5/8.
Her next step is to find a common denominator. Remember that if you multiply a number to the denominator, you'll have to multiply it to the numerator too:
1/3(4/4) + 1/4(3/3)
4/12 + 3/12
Simplify. Combine like terms
4/12 + 3/12 = 7/12
7/12 will be final solution
