Question

rational number between 1/5and 3/4​

Answer 1

To find any rational number between two of the number then

Let first number be A

And second number be B

So , here A = 1/5

And B = 3/4

and there is a formulae 1/2×(a+b)

$\frac{1}{2} \times ( \frac{1}{5} + \frac{3}{4} ) \\ \\ = \geqslant \frac{1}{2} \times ( \frac{4 + 15}{20} ) \\ \\ = \geqslant \frac{1}{2} \times \frac{19}{20} \\ \\ = \geqslant \frac{19}{40}$

Answer 2

LCM OF BOTH THE DENOMINATOR IS-----

(4;5)=

20

1/5 =1×4/5×4

3/4=3×5/4×5

1/5=4/20

3/4=15/20

4/20+15/20=14/20!!!!!

SO THE NUMBERS BETWEEN 4/20 AND 14/20 --------5/20;6/20;7/20;8/20;9/20........to 14/20
