Answer 2

Step-by-step explanation:

First take LCM two equal them then find the

answer aur by using n+1 formula

LCM of 4 and 5 is 20

So,

1/5x4-4/20

1/4x5-5/20

there are less number and is not essential for

8 number between the 2 no. so we use nt1

formula

as here we need a rational number between

two.

so the value of n here is 8

nt1-8+1-9

4/20x9-36/180

5/20x9-45/180

37/180, 38/180, 39/180, 40/180,41/180,

42/180, 43/180, 44/180

so, 8 numbers between 1/5 and 1/4
