"per cent" is short for "per centum" which is Latin for "per hundred".
 
So (1/8)*(100/100) = (100/8)/100 is 100/8 per hundred = 12.5%

Students having biggest episode about percentage. I tell him it is only converting cents to dollars, and vice Versa.

You can cross-multiply to convert fractions into percentages.
 
1      x
— = —
8     100
 
(100)1 = x(8)
 
100 = 8x
 
 
Isolate x by dividing both sides of the equation by 8.
 
100       8x
 —    =   —
(8)        (8)
 
100
 —   =  x
  8
 
 
Simplify.
 
12.5 = x
 
 
So one out of eight equals 12.5 out of a hundred, or
 
12.5 %
Here is another strategy.
 
1/8=1/(2*2*2)
Each 2 needs a 5 to make 10 because a terminating decimal can be written as a fraction whose denominator is a power of 10.
Multiply both numerator and denominator by 5*5*5 which equals 125.
1(125)/8(125)=125/1000=0.125
Move the decimal point two places to the right to get 12.5%
 
You can do what Kevin W. suggested; divide 1 by 8 and divide until the division stops or terminates. After that, as Kevin W. said, multiply by 100 or move the decimal point two places to the right and add the % symbol.
When dividing make sure that the numerator is on the inside of the division sign and the denominator is on the outside of the division sign.

8l 1.000     Add zeroes as you divide until the division process stops. I added three zeroes because I knew the division process would stop after three divisions because of the three 2's.(1000 is the smallest power of 10 divisible by 8) 
to convert a fraction to a percent simply divide the numerator by the denominator and multiply the answer by 100
 
1÷8 = 0.125
0.125 x 100= 12.5
 
so the answer is 12.5%
In order to answer this you take 1 divided by 8 then multiply by 100. the answer should be less than 100 if you did it properly.
