Let us first tell you why it is useful to know 25 as a decimal.
Typically, to calculate the 25 percentile, you would multiply a number by 25 percent and then you would take that product and divide it by 100 to get the answer.
Instead, you can multiply any number as a decimal by 25 to get the answer.
25 percent means 25 per hundred. So, to get 25 as a decimal, all you have to do is divide 25 by 100:
When you divide something by 100, move the decimal point two places to the left. Friends, you can see your answer on the calculator.
How to write in decimal form?
Fractions with denominators 10, 100, etc. can be written in a special form using the decimal point. In this form they are called decimal numbers the place immediately after the decimal point (i.e. the tenth place) has a place value, the next to it (i.e. the hundredth place) has a place value of -, and so on.
How to solve fraction?
To solve for a fraction, simplify the first fraction. Begin by finding the greatest common factor (GCF) of both the numerator and the denominator of the fraction the greatest common factor is a number by which both the numerator and the denominator can be divided. Then, simply divide the numerator and denominator by the greatest common denominator so that your fractions are simplified.
