10)

5 rational number between 5/6 and 6/7

   first we will same the denominator = 35/42 and 36/42

so, we add one in rational no. =5+1=6

according to question

 35/42 = 35 multiply by 42 and  multiply by 6

= 210/252 

like that, 36/42 =36 multiply by 6 and 42 multiply by 6

=216/252

so, 210/252 and 216/252

211/252, 212/252, 213/252, 214/252, 215/252
