## Reducing fractions *the wrong way*
In this code-golf challenge you have to find fractions that can be reduced the wrong way but still end up in the same number.

**Note:** reducing fractions *the worng way* does here have an exact definition, see details.

Example:

64/16 = <strike>6</strike>4/1<strike>6</strike>=4/1 = 4

Of course you cannot just strike both 6es but here you still end up with the correct value. In this challenge you have to find examples like this.

###Details
You have to write a function/program that accepts one positive integer `n` as input and outputs/returns a list/array of the fractions in format  
`numerator1,denominator1,numerator2,denominator2,...`

The program has to find out for each fraction `a/b` with `a+b=n` and `a,b>0` whether it can be reduced *the wrong way*. (It does not matter whether in can be reduced in the convential way or whether there are many possibilities of reductions, it just has to be possible to reduce it *the wrong way* in at least one way.)

**Definition of** ***the wrong way:*** A fraction can be reduced *the wrong way* if and only if you can the same sequence of digits appears in a and b *and* if the value of the fraction stays the same if you remove the substring.

Example: 1536/353 can be 'reduced'  to 16/3 but those two values are not equal so you cannot reduce this fraction *the wrong way*.

Note that this definition of reducing *the wrong way* can also include fractions that are reduced the right way: `110/10 = 11/1` is within the definition of reducing *the wrong way* even though it is a valid step.

### Scoring
The least number of bytes wins. You can write a function or program that accepts an integer and returns an array or a program that uses stdin/stdout or you can consider n saved in a variable and in the end of the program the list must be saved in an other variable.

### Test cases
Please include following testcases (Tell me which ones I should add, I have no idea how many of those fractions there are / how many examples to expect=)

    n=80 (64/16 should be in this list)
    n=147 (98/49 should be in this list)
    n=500 (294/196 should be in this list)
