I'm trying to teach myself maths and I'm stuck at this problem:(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Which of the following fractions is nearest to [tex]\frac{1}{2}[/tex]?

You must show your working.

[tex]\frac{3}{5}[/tex] [tex]\frac{7}{10}[/tex] [tex]\frac{11}{20}[/tex]

2. Relevant equations

3. The attempt at a solution

I know the answer is [tex]\frac{11}{20}[/tex], because it just is! What I don't know how to do is "show my working". I've tried searching for "find closest fraction to another fraction" but I can't seem to find the proper technique for calculating this. Any pointers will be gratefully received.
