How to Subtract Fractions?

Just like with addition of fractions, subtracting fractions with common denominators will just subtract the numerators and remain the denominator.

Similarly, with the case of fractions having unlike denominators, the least common multiple (LCM) should be get first then change the fractions into equivalent fractions with the LCM as the denominator. But these conditions are only applicable if the fractions are not mixed numbers.

Example 1

a. Solve: 2/5 – 1/4

Solution

First, make the denominators the same.

Logarithms - Properties of Logarithms

Multiply numerator and denominator of 2/5 and 1/4 by 4 and 5 respectively.

2/5× 4/4 = 8/20

1/4 x 5/5 = 5/20

Now do the subtractions:

8/20 − 5/20 =3/20

b. Subtract 3/8 from 7/8

Solution

7/8 – 3/8

= (7 – 3)/8

= 1/2
