decimal=decimal x 100/100=decimal x 100%
For instance
0.65=0.65x100%=65%
For a fraction, you should first convert to a decimal and then apply the same.

If u have a fraction and you want to turn it into a decimal then you need to divide the numerator by the denominator and get your decimal. To turn a decimal into a percent you move the decimal 2 places to the right. If you want to return the percent to a decimal then you take the percent and remember that the decimal is at the end of it and then you move the decimal 2 places to the left.

Decimal x 100 = %
(.50 x 100 = 50%)
Numerator divided by Denominator = Decimal
(3/4 = 3 (divided by) 4 = .75)
Percentage/100 = Fraction
(75% = 75/100; Finding lowest common denominator = 3/4)

For all the conversions, I would suggest that simple examples be considered.
The conversion rules can then be readily found.
Fraction to Decimal
1/4 = 0.25 and this is obtained by dividing top line by bottom line
Fraction to Percentage
3/5 becomes 3/5 x 100% = 3 x 20% = 60%
Rule is to multiply top line by 100 and then cancel
Decimal to percentage
0.8 = 80%
Rule is to multiply by 100
Percentage to Fraction
75% = 75/100 = 3/4
Rule is to express as a fraction with 100 as denominator and then cancel
Percentage to Decimal
60% = 60/100 = 0.6
Rule is to divide by 100
Decimal to Fraction
0.64 = 64 /100 = 32/50 = 16/25
0.8 = 8 /10 = 4/5
0.34 = 34 / 100 = 17/50
0.462 = 462/1000 = 231/500
Rule is to express as a suitable fraction and simplify

1st convert the decimal into a fraction
e.g 0.5 = 5/10
then 5*100/10
= 50 %

All you need to do is multiply by 100. For example. 0.15 becomes 0.15 multiplied by 100=15%. You do this for all decimals to convert them to a percentage value. Another example would be
0.3356= 0.3356* 100%=33.56%

50% = 50/100 = 1/2 or 0.5
140% = 140/100 = 7/2 or 1.40
Basically, take the percent/100 to get a fraction, then simplify.

Decimals to Percent:
Simply move the decimal point 2 spaces to the right.
E.g's: 0.25 = 25%; 3.65 = 365%; 0.1 = 10% ... etc.
