FRACTION DECIMAL PERCENT TABLE
Decimals, Fractions and Percentages are just different ways of showing the same value:
A Half can be written...
As a fraction: 1/2
As a decimal: 0.5
As a percentage: 50%
A Quarter can be written...
As a fraction: 1/4
As a decimal: 0.25
As a percentage: 25%
Example Values
Here is a table of commonly occurring values shown in Percent, Decimal and Fraction form:
Percent Decimal Fraction
1% 0.01 1/100
5% 0.05 1/20
10% 0.1 1/10
12½% 0.125 1/8
20% 0.2 1/5
25% 0.25 1/4
331/3% 0.333... 1/3
50% 0.5 1/2
75% 0.75 3 /4
80% 0.8 4/5
90% 0.9 9/10
99% 0.99 99/100
100% 1 1
125% 1.25 5/4
150% 1.5 3/2
200% 2 2
Converting Between Percentage and Decimal
Percentage means "per 100", so 50% means 50 per 100,
or simply 50/100.If we divide 50 by 100 you get 0.5 (a decimal number).
So, to convert from percentage to decimal: divide by 100 (and remove the "%" sign).The easiest way to divide by 100 is to move the decimal point 2 places to the left.
Example: Convert 8.5% to decimal
Move the decimal point two places: 8.5 -> 0.85 -> 0.085
Answer 8.5% = 0.085
Converting From Decimal to Percentage
To convert from decimal to percentage, just multiply the decimal by 100, but remember to put the "%" sign so people know it is per 100.The easiest way to multiply by 100 is to move the decimal point 2 places to the right.
Example: Convert 0.65 to percent
Move the decimal point two places: 0.65 -> 6.5 -> 65.
Answer 0.65 = 65%
To change a Decimal into a Fraction
Take the decimal, drop the decimal point, and place the result into the numerator of a fraction.
To determine the denominator , write a 1, followed by zeros --- as many zeroes as it takes to match the original length of the decimal.
Examples:
0.75 becomes 75/100
0.034 becomes 34/1000
2.5 becomes 25/10
