Additional comment

It can be useful to memorize the decimal equivalents of the reciprocals of the numbers up to 12.

  1/12 = 0.0833...(repeating 3)

  1/11 = 0.0909...(repeating 09)

  1/10 = 0.1

  1/9 = 0.111...(repeating 1)

  1/8 = 0.125

  1/7 = 0.142857...(repeating the same 6 digits)

  1/6 = 0.1666...(repeating 6)

  1/5 = 0.2

  1/4 = 0.25

  1/3 = 0.333...(repeating 3)

  1/2 = 0.5

Of course, any of these is expressed as a percentage by multiplying by 100%. 1/8 = 12.5%, 1/6 = 16.6...% (repeating 6)
