Rounding Fractions To The Nearest Whole Number 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: - Know More About Properties of rational number Tutorcircle.com Page No. : 1/4 -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.

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. Tutorcircle.com Page No. : 3/4 Page No. : 2/3 Thank You TutorCircle.com
