Rounding Fractions To The Nearest Whole Number

Before Rounding Fractions to the Nearest Whole Number, we should be familiar with the
whole number and fraction's terms.

 Fraction is ratio between the two integers and it is written in the form of p / q. for example
2 / 3, 5 / 6. And whole numbers are the natural numbers together with 0 forms the
collection of all whole numbers. Thus 0, 1, 2, 3, 4, 5...... All are the whole numbers.

Every natural number is whole number and it is to be noted that 0 is a natural number
which is not a natural number.

We round off the numbers so that we can make the calculations simpler and also for
easy understanding.

When we round off the numbers then we get the value that seems accurate value but
is is not, although it is very close to the actual value.

Rules for rounding fractions to the nearest whole number are: -

-First one is we have to convert the fraction value into the improper fractions or simply
get the answer of p / q fractions.

-Second one is we will check the fraction value with the ½ ( half ), if it is less than the
½ than no need to round off the whole number, so it will be the result means round off
value. If the fraction value is equal to the ½ and just next number after getting the
equality is less than ½ also than no change.

-Third one is, if it is greater than the ½ than we will add the 1 into the whole number
and we will leave the fraction number, so in this it will be the result means round off
value.

If the fraction value is equal to the ½ and just next number after getting the equality is
greater than ½ than increase by 1.

Let’s take some example for rounding fractions to the nearest whole numbers.

Example 1: - Determine the round off value of 9/2.
Solution: - First follow the step 1, the improper fraction value of this 4 ½.

Now follow the step 2, in this fraction value ½ is equal to the ½, so the result is 4.
This example can be solving by the other way.
The first step also says that we can get result of 9/2 to solve this, the result is 4.5
In this result we have .5 and just next number after getting equality is 0 that also
means no change in whole number, so the answer is 4.

Example 1: - Determine the round off value of 16/7.
Solution: - First follow the step 1, the improper fraction value of this 2 2/7.

Now follow the step 2, in this fraction value 2/7 is less than to the ½, so the result will
be 2.

Or in other way according to the first step we can get result of 16/7 to solve this, the
result will be 2.28

In this result we have .28 and that is less than the ½ that means no change in whole
number, so the answer is 2.

Like this we can solve any type of fraction value easily.
