3/5 = 3*7/5*7 => 21/35
4/5= 4*7/5*7 =>28/35
5 rational numbers are 22/35, 23/35, 24/35, 25/35, 26/35
4/5= 4*7/5*7 =>28/35
5 rational numbers are 22/35, 23/35, 24/35, 25/35, 26/35

I'll use two different methods in these two ques..u can try any one..for the first one i.e. 3/5 and 4/7 we see that the denominator isn't same, to make them same we will take out the LCM ...lcm of 5 and 7 is 35..so, 3/5*7/7 and 4/7*5/5 which is 21/35 and , we need three rational no. so we will multiply them by 4..so,
21/35*4/4=84/140 similarly 20/35 *4/4=80/140..
three rational no.are 81/140, 82/140 and 83/140
in second case since denominator is same u can multiply both of them with 10 , u get 30/50 and 40/50...so five rational no. are 31/50, 32/50,33/50,34/50 and 35/50..
hope i helped you..!!
