## Subtracting fractions

### Explanation:

| What do you get? ... Mmmh ... Four small pieces minus a large piece? .... Mmmh ...
| Here it is easy. The result is: "two pieces"!

We can only subtract pieces, that are the same size.
So, first we have to find a common denominator and convert all fractions.

### Steps:

- find the common denominator
- convert the fractions to the common denominator
- subtract the numerators
- if necessary reduce them

### A step by step example:

| These fractions don't have a common denominator, so to subtract them, we will first have to find a common denominator.
| Here you can see, how we have done this..
| This is the result you get.
| We can now subtract the numerators.

This is what it would look like in the JFractionLab.
