Convert Percent to Fraction

Word percent mean out of 100. Thus when the number 25 % is written, it indicates 25 out of 100. Now let us look at the method to convert Percent to Fraction. If any percentage is given, we will first write it in the form of the fraction, which will represent the number as the numerator and the digit 100 as the denominator. Now we will look into the   number, which has turned in the form of a / b. This value of a and b are the whole numbers where we have b <> 0.  Now the fraction so formed is in the lowest form or not. If not, we will convert the fraction in the lowest form. (know more about Fraction , here)
For this, we will find the HCF of both the numerators and the denominators. In case we get the HCF as 1, it indicates that the fraction so attained is in the lowest form else we will proceed to convert it in the lowest form. For this both the numerator and the denominator are divided by the hcf of the given number. If we have the percentage as 35 %, we will write this percentage as 35 / 100. Now we observe that the HCF of 35 and 100 is 5. So we will divide both the numerator and the denominator by 5 and we get:
35 / 100 = 7 / 20,  which is the required fraction number.
Here if we have to learn about the Temperature Conversion Formula, we will visit online math tutor, where we will learn about the method of converting the Celsius temperature to Kelvin or to Fahrenheit degree.   To know about the curriculum of Maharashtra State Board of Secondary and Higher Secondary Education, we will visit the website of the Maharashtra Board for the particular grade and particular subject and In the next session we will discuss about Is 1 a Prime Number
