Answer 11

Okay, it's helpful to know the decimal equivalents of some common fractions:

1/2 = 0.5
1/3 = 0.33333...
1/4 = 0.25
1/5 = 0.2
1/6 = 0.16666...
1/7 = 0.142857142857...
1/8 = 0.125
1/9 = 0.1111111...
1/10 = 0.1
1/16 = 0.0625
1/20 = 0.05
1/25 = 0.04
1/32 = 0.03125

2/3 = 2*1/3 = 0.666666...
2/5 = 2*1/5 = 0.4
3/5 = 3*1/5 = 0.6
5/6 = 5*1/6 = 0.83333...
2/7 = 0.285714...
etc.

So looking at your list, 62.5% is going to be some multiple of 1/16 = 0.0625
87.5% is a multiple of 0.125
33.3% should be obvious
83.3% is a multiple of 0.1666...

you can also just try multiplying the decimal by increasingly large integers on your calculator until you find one that makes the result "come out even"

3*0.333333 = 0.99999 -> that's exceedingly close to 1, so 1/3 would be the fraction.
