Basically what this is, is:

100% = 100/100

Basically, to get the fraction, you just set the denominator as 100 and move the percentage up. You can then multiply by as many powers of 10 as needed or simplify the fraction as many times as needed.

Ex:

78.7% = ?/100

Just put 78.7 into that question mark spot to get:

78.7/100 = 78.7%

Now, you multiply the whole thing by 10/10:

787/1000

So that's your fraction.

29% = ?/100

Then it would be,

29/100.

55.8%: 558/1000, you could simplify that by dividing both the numerator and denominator by 2, and you would get 279/500.

28.2%: 282/1000, simplify that: 141/500

82%: 82/100, 41/50

74%: 74/100, 37/50

91.8%: 918/1000, 459/500

72%: 72/100, 18/25

129%: 129/100

15.8%: 158/1000, 79/500

24.3%: 243/1000

93%: 93/100
