Note: What you do to the denominator, you must do to the numerator.
If there is an equal sign, and there are fractions on both side, what you do to one side, you do to the other.

Simplify:

-----------------------------------------------------------------------------------------

Take for example, a question such as:

7 3/10 - 9/20

First, change the mixed fraction into improper fraction:

7 = (7/1) * (10/10) = 70/10 + 3/10 = 73/10

Find common denominators. Remember that what you do to the denominator, you do to the numerator. Multiply 2 to both numerator and denominator:

(73/10)(2/2) = (146/20)

Simplify. Combine like terms

146/20 - 9/20 = 137/20

Simplify.

137/20 = 6 17/20

6 17/20 would be your answer for the example question.
