I plugged your numbers in and got about 0.2:
They show you the exact result as a fraction since to get an exact decimal representation would take too many places to show (or it may be a repeating decimal).

Your OP that says that the answer is 0.2 cannot be true since 0.2 is 1/5.
If you multiply the numerator by 5, then you should get exactly the denominator if the answer is 0.2. But that cannot be since 5*(...7121) ends in a 5. For 0.2 to be the answer, you would expect that the multiplication would end in many 0's.

phoffric How did you do it ?? did you use Mathematica program or on the web ?
im using Mathematica 8.0
And as it been shown in your image i get the second step , (the same numbers ) i don't know how to get the decimal approximation as in your image

This link Exact and Approximate Results shows how to get the results you want. This is for version 9, but I would not expect major changes in this area.
