In the example 1 3/4, 3 is the numerator.
For example, 4 is the denominator in the mixed fraction 1 3/4.
For example to find a lowest common denominator for 15/4 - 3/2, multiply the 15 and 4 by 2 and multiply the 3 and 2 by 4. You should get 30/8 - 12/8. Then you can subtract the fractions. If the denominators of both fractions are the same, you can skip this step.
For example, 30/8 - 12/8 = 18/8.
For example, 18 ÷ 8 = 2 with a remainder of 2. This can be written as 2 2/8.
The fraction in the example 2 2/8 can be reduced by 2 to get 2 1/4. Keep in mind that in some cases, you may not have a remainder.
Do 3 - 1 to get 2.
For example, multiply 3 and 4 by 2 to get 6/8. For the other fraction, multiply 1 and 2 by 4 to get 4/8. If your fractions have the same denominator, you can skip this step.
For the equation 6/8 - 4/8, subtract 4 from 6 to get 2/8.
For 3 3/4 - 1 1/2, you’ll get 2 2/8. Simplify 2/8 by 2 to get 1/4. Your finished answer will be 2 1/4.
