Question

Find the rational no. between 8and 9

Answer 1

Solution:

We know,

8 = 8/1 and 9 = 9/1

Now, we can write them as

$\frac{8}{1} \times \frac{10}{10 \: } \: and \: \frac{9}{1} \times \frac{10}{10}$

which gives

$= \frac{80}{10} \: and \: \frac{90}{10}$

$= \frac{80}{10} \: and \: \frac{90}{10}$

Hence, the rational number between them are 81/ 10 , 82/ 10 , 83/ 10 , 84/ 10 ..... so on.

Sometimes question are asked like

==> Example:-

Ques Find 5 rational numbers between 8 and 9.

So to solve such questions all we need to do is multiply the numerator & denominator by any number. If question asks to find 5 rational numbers then you can multiply it by 6 or you can also take up 10 for ease of calculations. We just need to make numerator & denominator of both the numbers equal.
