Question

find three rational number between 1/3 and 1/5 in 9th class

Answer 1

$\textbf{Given Numbers :}$

$\dfrac{1}{3} = \dfrac{5}{15} = \dfrac{10}{30}$

$\dfrac{1}{5} = \dfrac{3}{15} = \dfrac{6}{30}$

【LCM of 3 and 5 = 15】

Hence, three rational numbers between $\dfrac{1}{3}$ and $\dfrac{1}{5}$ are

$\dfrac{7}{30} , \dfrac{8}{30} , \dfrac{9}{30}$

$\textbf{Explaination -}$

First of all, we need to look at the dinominators of the given numbers, that they are equal or not.

If they are not equal then we have to make them equal by LCM method.

Then we have to see, that is it possible to get 3 rational numbers between them.

If no, then we have to multiply with a number in such a way, that we should get 3 rational numbers between them.
