## Adding Fractions

We think that the easiest way to add fractions is to use common denominators. To add fractions using common denominators, you first find the common denominator and whatever you do to the denominator, must be done to the numerator. So if you multiply the denominator by 6 you must multiply the numerator by 6 too. After this, add the numerators together and that's it!

## Multiplying Fractions

Multiplying fractions is pretty easy. The most common way is to Multiply your denominator by the denominator and your numerator by the numerator. Example; 5/6 x 2/5 so you would do 6 x 5 which is 30 and 5 x 2 which is 10, so the answer would be 10/30 or if you reduce it the answer would be 2/6.

## Dividing Fractions

Dividing fractions is easy if you can multiply them. What you do is say you have 4/6 divided by 6/2 you would switch the numbers around for the second fraction. Now your question would be 4/6 divided by 2/6. Now you would do just multiplication. Now it is numerator x numerator and denominator x denominator so it would be 4x2 is 8 and 6x6 is 36. So your answer would be 8/36 and you can reduce it down.

## Subtracting Fraction With Different Denominators

Subtracting fractions is almost the exact same as adding. Follow the same steps as adding (using the common denominators strategy). Once you have your new fractions with common denominators, just subtract the numerators!

## Equivalent Fractions

You have two fractions. When you divide or multiply the numerator and the denominator, the fraction keeps its value. For example, 1/2 and 2/4 are equivalent fractions because if you multiply 1x2 and 2x2 you get 2/4 and if you divide 2 by 2 and 4 by 2 you get 1/2.
