To subtract fractions with different denominators, you need to follow these steps:

Find the least common denominator (LCD) of the fractions.

Convert each fraction to an equivalent fraction with the LCD as the denominator.

Subtract the numerators of the equivalent fractions.

Write the result as a fraction with the LCD as the denominator.

Here’s an example:

Subtract 1/3 – 1/5

Step 1: Find the LCD of 3 and 5, which is 15.

Step 2: Convert the fractions to equivalent fractions with the LCD of 15:

1/3 = 5/15

1/5 = 3/15

Step 3: Subtract the numerators:

5/15 – 3/15 = 2/15

Therefore, the difference between 1/3 and 1/5 is 2/15.

The general steps are:

Find the LCD of the denominators.

Convert each fraction to an equivalent fraction with the LCD as the denominator.

Subtract the numerators of the equivalent fractions.

Write the result as a fraction with the LCD as the denominator.

This method ensures that the fractions have a common denominator, allowing you to perform the subtraction directly on the numerators.
