How to Convert Percentage into a Decimal?
To convert easy and simple points and guidelines to convert percentages to decimal values. The step by step procedure is as follows:
- First of all, know the value and obtain the percent which has to be converted to the decimal value.
- Now, ignore the percentage symbol and simply divide it with 100
- Finally, express the given fraction in the decimal value which is the final decimal value.
Ways to Turn a Percent into a Decimal
There are various ways to convert the percentage to decimals. They are:
1. Divide by 100
Mostly the interest rates are advertised and quoted in percentage terms. But, to find the exact value, we have to convert them to decimal format. The easiest way to convert the percentage to decimal is to divide the value by 100.
2. Move the Decimal Point to the Left
There is also another way by which the percentage can be converted to decimal values, that is to move the decimal point to the left side. This method is the easiest of all the methods, once to practice this method thoroughly, you can easily solve the equation in your mind without using pen and paper.
If the number does not have the decimal value, we can assume that it has the decimal value at its end or the direct right side of the number. Assume that the decimal value is followed by 2 zeroes. For example, if 65 is the number then the decimal value of that number is 65.00
Few examples of moving the decimal value over 2 places are:
- 200% = 2.00
- 250% = 2.5
- 68.678 = .68678
- .8% = .008
Most of these financial calculations give only a rough idea of the amount you earn or spend. But these calculations are widely used in making quick and useful estimates. To convert the percentage into decimal values, these methods are accurate and it is also important the usage of the values after conversion.

Percentage to Decimal Conversion Examples
Express the following Percentage into Decimal
Convert 29% into decimal value?
To convert a percentage to decimal values are very easy. The given value in the question is 27%.
In the first step, drop the “%” character and move the decimal point to the left of two places.
27% = 0.27
In a video game, Val scored 30% fewer points than Rancho. Rancho scored 1060 points. How many points did Val score?
As given in the question,
No of points Rancho scored = 1060
No of points Val scored = 30% fewer than Rancho
Therefore, total points Val scored = 0.3(1060)
From the above data, the equation will be as
1060 – 0.3(1060) = 742
If we consider the Rancho’s score as 100%, then the score of Val = 100% – 30% = 70%
To find the score of Val, we write the equation as 1060(70%)
= 1060 * 0.7 = 742
The decimal value of Val’s score = 742.0
Thus, the score of the Val = 742.0
There are 20% more spades than hearts in the poker set. There are 220 spades and hearts altogether in the poker set. How many spades are there in the poker set?
Let Spades be S and Hearts be h
As given in the solution,
S + H = 220
H = S + 220
H = 220S
1S + 1.2S = 220
2.2S = 220
Divide the equation by 2.2
2.2S / 2.2 = 220/2.2
Hearts = 100
Spades = (1.2)(100) = 120
Therefore, the number of spades in the set is 120
Thus, the final solution is 120 spades
Cameroon was 165cm tall on the initial day of college this year, which was 10% taller than he was on the initial day of college last year. How tall was Cameroon on the initial day of college last year?
As given in the question,
Height of Cameroon on the initial day of college this year = 165cm
Height of Cameroon on the initial day of college last year = 10%
Let the height of Cameroon = x
1x + 0.1x = 165
1.1x = 165
Divide the equation with 1.1
x = 150cm
Therefore, Cameroon was 150 cm on the initial day of college last year
Thus, the height of Cameroon on the initial day of college last year = 150cm
