One quality as a percentage of another
  1. Sometimes you need to write one quality as a percentage of another.
    1. Example
      1. Write 25cm as a percentage of 3m.
        1. Firstly check that the units are the same, and change if necessary: 3m=300cm
          1. Now write as a fraction: 25/100
            1. Now multiply by 100%: 25/100 x 100% = 8.333333...%
