Fractions consist of two numbers. The top number is called the numerator. The bottom number is called the denominator.
To subtract two fractions with the same denominator, subtract the numerators and place that difference over the common denominator
To Subtract Fractions with different denominators:
Find the Lowest Common Denominator (LCD) of the fractions
Rename the fractions to have the LCD
Subtract the numerators of the fractions
The difference will be the numerator and the LCD will be the denominator of the answer.
Simplify the Fraction

Subtract the second numerator from the first
Place that difference over the common denominator.
