Question

How we can find which number is rational and which is irrational ​

Answer 1

Answer:

RATIONAL NUMBERS

       A rational number is a number that can be written in the form  $\frac{p}{q}$, where  p  and  q  are integers and  q ≠ o .Since any integer can be written as the ratio of two integers, all integers are rational numbers. Remember that all the counting numbers and all the whole numbers are also integers, and so they, too, are rational.

IRRATIONAL NUMBERS

        An irrational number is a number that cannot be written as the ratio of two integers. Its decimal form does not stop and does not repeat.

        Let’s summarize a method we can use to determine whether a number is rational or irrational.

If the decimal form of a number

• stops or repeats, the number is rational.

• does not stop and does not repeat, the number is irrational.

Answer 2

Answer:

you can do so by the help of the no given to you

Step-by-step explanation:

for example: if 12 is the no. given to you the it is rational

or if 1.11456 is the no. given then to it is rational also if the number is 2/5 then too it is rational as the the numbers after the decimal point is not recurring but if nos are repeating itself after the decimal in continuous fashion the it irrational for example 59.3737373.............. similarly there is a line or a dot on the recurring no. instead of '.......' in this way you can identify if the number is rational or irrational
