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)
