How to convert fractions to mixed numbers

To convert a fraction to a mixed number, follow these steps:

  • First take the numerator and divide it by the denominator.
  • The integer part will be the integer in the mixed number.
  • The remainder will be the new numerator of the fraction.
  • The denominator remains the same.

For example: Given the fraction 9/2, express the above fraction as a mixed number.

How to do it:

  • Step 1: Take the numerator and divide it by the denominator, that is, take 9 : 2 = 4 and the remainder is 1.
  • Step 2: The result of the division by 4 is the integer part of the mixed number, the remainder is 1 and will be the new numerator.

The mixed number obtained is:

Note:

  • Any fraction with a numerator larger than its denominator can be converted to a mixed number and vice versa.
  • However, if the numerator is equal to or less than the denominator, it cannot be done.

Method 2: Add the integer part with the integer part, the fractional part with the fractional part

We separate the integer part to perform addition or subtraction, then perform the same calculation with the fraction part. This method only applies if the 2 mixed numbers are not negative.

How to multiply and divide mixed numbers

  • Add or subtract mixed numbers by writing the mixed number as a fraction and then adding or dividing the fraction.
  • When multiplying or dividing a mixed number by a whole number, we can write the mixed number as a sum of a whole number and a fraction.
