Question

insert 16 rational number between 2.1 and 2.2

Answer 1

2.1 + 2.2/2
=4.3/2= 2.15
then take 2.1 and 2.15
2.1+2.15/2=2.125
and so on just like you can find 16 more rational number between 2.1 and 2.2

Answer 2

2.1= 21/10
2.2= 22/10
21/10 *17 = 357/170
22/10*17= 374/ 170
357/170, 358/170, 359/170, 360/170, 361/170, 362/170, 363/170, 364/170, 365/170, 366/170, 367/170, 368/170, 369/170, 370/170, 371/170, 372/170, 373/170, 374/170...
