For example, in the fraction 1/5, 1 is the numerator.
For example, in the fraction 1/5, 5 is the denominator so there should be 5 parts in the fraction.
For example, 3/4 is a proper fraction and 5/3 is an improper fraction. If you have a whole number with a fraction, it’s called a mixed fraction. For example, 1 1/2 is a mixed fraction.
For example, to find a common denominator for 1/3 + 2/5, multiply the 1 and 3 by 5 and multiply the 2 and 5 by 3. You should get 5/15 + 6/15. Then you can calculate the fractions.
For example, 3/6 - 2/6 = 1/6. Avoid adding or subtracting denominators.
For example, to multiply 2/5 by 7, turn 7 into a fraction. Then you can multiply 2/5 by 7/1. If you have a mixed fraction such as 1 1/3, turn it into an improper fraction, 4/3 before you multiply.
For example, to multiply 1/3 by 3/4, multiply 1 by 3 to get the numerator. Multiply 3 by 4 to get the denominator. Your answer will be 3/12.
For example, if your answer is 3/12, 3 is the greatest common factor. Reduce the fraction by 3 to get 1/4.
For example, with 5/4 ÷ 1/2 you should flip the 1/2 fraction so it appears as 2/1.
To continue the example, you’d multiply 5/4 by 2/1 to get 10/4.
For example, the greatest common factor for 10/4 is 2 so your simplified answer is 5/2. Since this is an improper fraction, turn it into a whole number with a fraction. 5/2 becomes 2 1/2.
