Are you one of those individuals who want to learn how to calculate fractions? Look no further, as below we will explain the methods of adding, subtracting, multiplying, and dividing fractions.

Adding Fractions

  • First of all, identify the least common denominator (LCD).
  • Find the number you require to multiply the denominator by to get the result in the least common denominator for your first fraction.
  • Now, you need to multiply that number by the numerator and denominator.
  • Repeat steps 2 and 3 for every single fraction.
  • For adding fractions, add the fraction numerators.
  • Transform improper fractions to mixed numbers.
  • Reduce the fraction to the lowest terms.

Formula for Adding Fractions

a b + c d = a d + b c b d


Below is an example of adding fractions:


a = 3, b = 6, c = 2, d = 4

3/6 + 2/4 = {(3×4) + (6×2)} / 6×4

12 + 12 / 24

24 / 24


Subtracting Fractions

  • To subtract fractions, first find out the least common denominator.
  • Then, identify the number you suppose to multiply the denominator by to result in the least common denominator.
  • Now, multiply the numerator and denominator by that number.
  • Repeat steps 2 and 3 for every fraction.
  • For subtracting fractions, subtract the fraction numerators.
  • Transform improper fractions to mixed numbers.
  • Reduce the fraction to the lowest terms.

Formula for Subtracting Fractions

a b c d = a d b c b d


Here are the following examples of subtracting fractions.


a = 3, b = 6, c = 2, d = 4

3/6 − 2/4 = {(3×4) − (6×2)} 6×4

12 - 12 / 24


Multiplying Fractions

  • First, multiply all numerators together.
  • After that, multiply all denominators together.
  • Reduce the result to the lowest terms.

Formula for Multiplying Fractions

a b × c d = a c b d


Here is the example of multiplying fractions shared below.


a = 3, b = 6, c = 2, d = 4

3/6 x 2/4 = 3×2 / 6x4


6 ÷ 6 / 24 ÷ 6

1 / 4

Dividing Fractions

  • To divide the fractions, you need to restructure the entire equation as in "Keep, Change, Flip"
  • Keep the first fraction as it is
  • Then, simply change the division sign to multiplication.
  • Lastly, flip the second fraction by swapping the top and bottom numbers.
  • Now, multiply all numerators together.
  • After that, multiply all denominators together.
  • Reduce the result to the lowest terms.

Formula for Dividing Fractions

a b ÷ c d = a d b c


Here is an example of dividing fractions.


a = 3, b = 6, c = 2, d = 4

Add the values in the formula,

3/6 ÷ 2/4 = 3×4 / 6×2

3/6 x 4/2

(3 x 4) / (6 x 2)



Mixed Number Fraction Calculation

What is “OF” term in Fraction?

In this question, the term “OF” means multiplication,

For Example, 3/4 of 5/11

In this, you need to multiply to solve 3/4 × 5/11.

So, here is the solution:

For fraction multiplication, multiply the numerators and then multiply the denominators to get

3×5 / 4×11 = 15 / 44

This fraction cannot be further reduced.


3/4 of 5/11 = 15/44
