Subtraction of Fractions You subtract the same way you add them. Subtract the numerators and put the answer over the common denominator. Do not subtract the denominator! 3/4 – 1/4 = 2/4 5/6 – 3/6 = 2/6 You try this one. 8/9 – 5/9 =________ Write the problem with the answer on a note card and give it to your teacher. She will give you a treat if you have the right answer!

Rule: Whatever you multiply the numerator by you must multiply the denominator by the same number. The picture below shows two different fractions that are equal to a half. All you have to do is multiply the numerator (top number) and the denominator (bottom number) by the same value and you have an equivalent fraction. 1/2 2/4 1x2=2 2x2=4

Multiplying Fractions When multiplying fractions, we multiply the two numerators and the two denominators. That gives us a product on top and another product on the bottom. Check out the following examples. http://www.mathsisfun.com/fractions_multiplication.html You will need to simplify your answers.
