WebIt is a rational number. In general, any decimal that ends after a number of digits (such as 7.3 7.3 or −1.2684) −1.2684) is a rational number. We can use the place value of the last digit as the denominator when writing the decimal as a fraction.
WebYes! When we add or multiply two rational numbers, we'll always get a rational number as the result. But when we add or multiply a rational number with an irrational number, we'll end up with an irrational number. Learn more with our Proof: sum & product of two rationals is rational video.

Difference Between Rational And Irrational Numbers - BYJU'S
WebThe main difference between rational and irrational numbers is that rational numbers are numbers that can be stated in the form of \ (\frac {p} {q}\), where \ (p\) and \ (q\) are integers and \ (q\neq 0\), whereas irrational numbers are numbers that cannot be expressed so (though both are real numbers).
