Subtracting Fractions with Like Denominators:
Remember that given a fraction, such as
, the top number is the numerator (namely 1) and the bottom
number is the denominator (namely 2)
Example 1:

Whenever you subtract fractions with like denominators, you subtract the numerators to create the answer numerator, and use the same denominator as the answer denominator.

Example 2:

Whenever you subtract fractions with like
denominators, you subtract the numerators to create the answer
numerator, and use the same denominator as the answer
denominator. In this case you must also
reduce your final fraction.

Don’t forget to reduce your answer to lowest terms,
i.e.
