Rounding Fractions to the Nearest Whole Number?

       
           

We call fractions as parts of whole numbers. Any fraction number can be expressed in form of a / b, where we say that numbers 'a' and 'b' are whole numbers such that b <> 0. Let us now learn rounding fractions to the nearest whole number.
For this we will first convert fraction in form of decimal number. Fraction numbers can be of two types: Proper fraction and Improper fraction number. We must remember that proper fraction number is always less than 1 and improper fraction numbers is always greater than 1.

Now when we convert given fraction in form of decimal, we will check the digit at tenth place of decimal number so formed. If the digit at tenth place is less than 5, then decimal part of number will be omitted and whole part is required whole number.
On the other hand, we say that if digit at tenth place is 5 or more, then we will omit the decimal part and number 1 will be added to whole number to get the nearest whole number equivalent to given whole number.

Let us make concept more clearly with following examples. If we have a fraction number 3 / 4, we write it in form of decimal as 0.75. Now we observe that tenth place digit is 7, which is more than 5, so 1 is added to whole number 0 of number 0.75 and we will get the whole number as 0 + 1 = 1.
Similarly if we have 1 /4, it is written as 0.25, here we have 2 at tenth place. So we will simply omit the decimal part and whole number will be ‘0’.
