Answer:
Denominators of 3/8 and 2/5 are not equal.
LCM of 8 and 5 is 40
3/8 × 5/5 = 15/40
2/5 × 8/8 = 16/40
Between 15/40 and 16/40 there are no rational numbers. We need 1 rational between these two rational numbers. So we should multiply them with next number, which is 2.
15/40 × 2/2 = 30/80
16/40 × 2/2 = 32/80
31/80 is the rational number between 3/8 and 2/5
