Adding Fractions with different denominators! Adding fractions with different denominators is similar to adding fractions with the same denominators, but there are rules you need to follow to add fractions correctly. To add fractions
 * it is necessary to change fractions to equivalent fractions if they are not already. You need to find a common denominator.
 * add the fractions by adding the new numerators. **The denominator stays the same!**

1) Mario serves pizza cut into 8 pieces, so that each piece is exactly 1/8 of the pizza.

At one table Sam eats 3/8 and Pam eats 2/8 of their pizza.

How much of the pizza did Sam and Pam eat together?

2) Three friends go shopping to buy a CD player fro a birthday present. An elecrtic store offers it fo rhalf price.

What fraction of the original price does each of them contributr if they share the cost equally?

3) In his will, an old man leaves 1/3 of his fortune to his best friend, 1/4 of it to his favourite football club, and the rest is left to charity.

What fraction of his fortune is left to charity?

=** Subtracting Fractions with different denominators! **=

In order to subtract two or more fractions you need to change the fractions to equivalent fractions with a common denominator. The next step is to subtract the fractions by subtracting the new numerators. the denominator stays the same.

Subtracting fractions with different denominators works very similarly to adding fractions with different denominators. Let’s say you have a problem that looks like this:

............................................................................ 3/4 - 1/2

First, you need to find common denominators. For this problem, we find our common denominator to be 4, so we change both fractions to have denominators of 4. Then, our problem looks like this: ............................................................................. 3/4 - 2/4

Now, you subtract the numerators, so 3 – 2 = 1.

Keep the denominator the same: 4. You do not subtract the denominators. Thus, your answer is 1/4.

Make sure your answer is reduced all the way. (this one doesn’t need to be reduced because it’s in its simplest form) and you’re done!
