Question

Can a number be both rational and irrational

Answer 1

A rational number is a number which can be expressed as a fraction whose numerator and denominator are both integers and whose denominator is not equal to zero. Rational numbers include all integers, fractions, mixed numbers, and some decimal numbers.

 

Note : All terminating and repeating decimal numbers are rational numbers because those numbers can be expressed as a fraction. On the other hand, a non repeating number and non terminating decimal, like square root of 2, is an irrational number.

rational numbers:whole numbers,integers,repeating and termunating decimals
1/2,2,3.5,0.1,and perfect sqaures

irrational numbers:
