Q.4. Which of the following is a rational number between 2/9and1/( 3)?
(a) 23/90(b) 29/90 (c)7/30 (d) All of these.

Answer 1

2/9 and 1/3

by taking LCM=9

we get 2/9 and 3/9

now multiply both numbers by 10/10

we get,

20/90 and 30/90

as you can see 23/90 and 29/90 are  present between the two numbers

Also 21/90=7/30 (divided by 3) is also present

So the answer is all of these
