let LCM of 2/5 and 3/7 is 35, then, 2/5 * 7/7 and 3/7 * 5/5          = 14/35   and  15/35 now to get 3 rational number between 2/5 (14/35) and 3/5 (15/35) are we have to multiply 4 (3+1) to the numerator and denominator then, 14/35 * 4/4 and 15/35 * 4/4             = 56/140  and  60/140 hence the 3 rational numbers  between 2/5 (56/140) and 3/5 (60/140) are  57/140 , 58/140 , 59/140
