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.

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
