Subtracting fractions with the same denominator (bottom number) is easy. When the denominators are the same, you can just think of the fractions as pieces of cake.
To subtract one fraction from another when they both have the same denominator, subtract the numerator (top number) of the second from the numerator of the first and keep the denominator the same. For example:
Sometimes, you may have to reduce:
Because the numerator and denominator are both even, you can reduce this fraction by a factor of 2:
Unlike addition, when you subtract one proper fraction from another, you never get an improper fraction.
