For percentages, put what you want to find out in words.
"What percent of 8 is 1"
Now write it mathematically:
what = x
per = /
cent = 100
of = *
8 = 8
is = '='
1 = 1
Putting it all together:
x/100 * 8 = 1
If you re-arrange it for x, you find:
x = 1/8 * 100
x = 12.5%
The words-to-numbers tricks work with EVERY single percentage question.
1/8 x 100%
= 100/8 %
= 12 1/2 % (12.5%)
easy mate the right one is 12.5% i know because if 8 represents 100% then 4 would represent 50% and 2 would represent 25% and 1 would represent 12.5% its just basic division hope this helps you out
1/8 x 100 =12.5.. u can do it on calculator
1/8 x 100% =12.5%
Depending upon your skills, here is another way to do it...
If you already know that 1/4th is 25% than 1/8 is half of 25% or 12.5%.
this is very simple dont get confused. 1/8 = 12.5 %
Method
1/8 as a percentage = (1/8 ) * 100
Always remember when you convert from fraction to percentage, just times 100% to your fraction
1/8 or 0.125
when you convert to percentage
0.125 * 100% = 12.5%
when you want to convert percentage to fraction (divide by 100%)
12.5% / 100% = 0.125
1/8 = 0.125. That's 125-thousandths. To make it hundredths (%), just move the decimal so you have hundredths...12.5 hundredths, so 12.5%
1/8 = 0.125 = 12.5 %
