Question

Write three rational numbers that lie between 3/9 and 5/9. pls give step by step explanation​

Answer 1

Answer:

Rational no between 3/9 and 5/9.

To find rational no's. the formula is (a+b)/2

let a = 3/9 and b= 5/9

then [3/9 + 5/9]/2 = (7/9)/2 = 7/18.(i.e 1st rational no.)

now, a=3/9 and b= 7/18

[3/9 + 7/18]/2 = [13/18]/2 = 13/36(i.e 2nd rational no.)

now a= 3/9 and b = 13/36

[3/9 + 13/36]/2 = [25/36]/2 = 25/72(i.e 2rd rational no.)

Therefore, the three rational no's are.. 7/18 , 13/36 , 25/72.
