1. Find a common denominator. If you are not good with numbers and you don't understand what the Least Common Denominator (LCD) is, just multiply the two denominators.

2. Find equivalent fractions that have the common denominator found in step 1. If you are not good with numbers, multiply each numerator by the denominator of the other fraction.

3. Add or subtract the new numerators.

4. Put the new numerator over the common denominator.

Numerator = number on the top

Denominator = number on the bottom

Example: 1/2 - 1/5

1. Common denominator = 2 x 5 = 10

2. 1/2 = (1 x 5)/10 = 5/10, 1/5 = (1 x 2)/10 = 2/10

So now we have 5/10 - 2/10 instead of 1/2 - 1/5

3. 5 - 2 = 3

4. 3/10

### What are the steps to subtracting fractions?

Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.

### When adding two fractions with unlike denominator's which of these steps is the first step?

The first step is to make the denominators the same.

### What are the steps needed to add or subtract fractions with unlike denominator?

First you find the common denominators, here is an example: 4/5 - 3/8. You have to make them both have the same denominator, Here is what you would do: Multiply 4/5 by 8/8 and you'd get 32/40, now you would take 3/8 and multiply it by 5/5 and get 15/40. 32/40-15/40 is a lot easier

### Are the steps for like and unlike denominators the same or different?

It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.
