Difference between rational and irrational numbers class 9

Rational and irrational numbers comprise the real number system. This Venn diagram shows a visual representation of how real numbers are classified. These are all positive, non-decimal values starting at one. Whole numbers are the natural numbers plus the value of zero. The integer set of numbers includes whole numbers and all negative, non-decimal values. Rational numbers include the sets seen here in addition to the fractional values in between. An easy way to remember this is that the word ratio is in the name of this classification. All numbers included in the rational number set can be written as a ratio of integers:. Clearly, the set of integers can be written as ratios because any integer divided by 1 results in the original integer. As illustrated here, integers can be expressed as fractions in infinite numbers of ways. Fractions can also be written as decimals. For example:. These decimals can be written as fractions, so they are considered rational.

Difference between Rational Numbers and Irrational Numbers. We can represent rational numbers in the form of the ratio of two integers positive or negativewhere the denominator is not equal to 0.
