How to subtract rational expressions with different denominators - GRE Quantitative Reasoning

To simplify this expression, first multiply both terms by the denominator of the other over itself:

Now that you have a common denominator, you may subtract:

To solve this problem, first multiply each term of the original expression by the denomenator of the other over itself:

Then you will have two terms with a common denomenator:

Combine the terms and simplify for your final answer:

To simplify this problem, multiply each term by the denomenator of the other over itself:

Then you will yield terms with a like denomenator, which can be combined:
