Question

find three rational numbers between 3by5 and 2by3​

Answer 1

A rational number between 2/3 and 3/5 is 1/2 (2/3 + 3/5) = 1/2( [10+9]/15 ) = 1/2(19/15) = 19/30

Then, 2/3 < 19/30 < 3/5

A rational number between 2/3 and 19/30 = 1/2 {2/3 + 19/30} = 1/2 ([20+19]/30) = 1/2(39/30) = 39/60

A rational number between 19/30 and 3/5 = 1/2 {19/30 + 3/5} = 1/2 ([19+18]/30) = 1/2(37/30) = 37/60

Therefore, 2/3 < 39/60 < 19/30 < 37/60 < 3/5

Hence, 39/60, 19/30 and 37/60 are the three rational numbers lying between 2/3 and 3/5.

Answer 2

Answer:

3/5 and 2/3

L.C.M of 3/5  and 2/3 = 15

3/5*3/3    2/3*5/5

9/15           10/15

9/15*4/4    10/15*4/4

36/60         40/60

three rational numbers between 3/5 and 2/3 are 37/60 , 38/60 ,  39/60
