Respuesta :

Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator like this:
1.Find the smallest multiple (LCM) of both numbers.

2. Rewrite the fraction as equivalent fraction with the LCM as the denominator.

Answer:

Adding and subtracting fractions are easy.

Step-by-step explanation:

All you need to do is find a common denominator for both fractions.

For example;

6/12 + 1/2 = 1 or

1/2 + 1/2 + 2/2

This also works for subtractions:

6/8 + 3/4 = 1 2/4 or

3/4 + 3/4 = 1 3/4
