Question

. Find three different rational no. between 5 upon 7 and 9 upon 11

Answer 1

5/7 and 9/11

LCM OF 7 AND 11=7*11=77

5/7*11/11=55/77

9/11*7/7=63/77
So between these 2 rational forms, many fractions are possible
For example

55/77, 56/77, 57/77, 58/77, 60/77, 62/77, 63/77

Or

5/11, 56/77, 57/77, 58/77, 60/77, 62/77, 9/11

Hope this helps
