Question

find the three rational numbers 1/5and 1/4

Answer 1

On taking the LCM of denominators I.e 5 and 4, we get 20.

Multiply both 1/5 with 4/4 and 1/4 with 5/5 to get the same denominator 20.

Now the fractiona are 4/20 and 5/20.

Multiply them with 10 /10 or 100/100 according to our convinence.

4/20 × 10/10 = 40/200
5/20 × 10/10 = 50/200.

Now three rational​numbers between them are

41/200, 42/200, 43/200.

Like that you can write many...
