To find find a rational between root2 and root3 we need to be clear about the definition of Rational number
What is a rational number?
A rational number is a number that can be expressed in the form of x/y, where y must not be 0. (x and y being integer)
A rational number between √2 and √3 is 1.5
Let us understand with explanation.
Explanation:
If we divide a rational number we get a number in either repeating decimals or terminating decimals.
On expressing √2 in decimals we get non-recurring and non-terminating decimals as √2 is an irrational number.
Similarly, on expressing √3 in decimals we get non-recurring and non-terminating decimals as √3 is an irrational number.
√2 = 1.414 (rounded to 3 decimal places) and √3 = 1.732 (rounded to 3 decimal places).
Below are the 3 decimal places rounded numbers in between 1.414 and 1.732
