61 / 90, 62 / 90, 63 / 90, 64/90, 65/90
Explanation:
2/3 = 2 x 5 / 3 x 5
= 10 / 15
4/5 = 4 x 3 / 5 x 3
12 / 15
we can find 5 rational numbers betwen 2/3 and 4/5 by multiplying them with 5 + 1 = 6
10 / 15 X 6 / 6
= 60 / 90
12 / 15 X 6 / 6
= 72 / 90
the rational numbers = 61 / 90 62 / 90 63 / 90 64/90 65/90

31/45, 32/45, 11/15, 34/35, 7/9.
Step-by-step explanation:
The LCM of 3 and 5 is 15 so we can write 2/3 and 4/5 as:
10/15 and 12/15 so one rational number between these is 11/15.
Now 11/15 = 33/45 and 4/5 = 36/45
So 2 rationals between these are 34/45 and 35/45 = 7/9
2/3 = 30 / 45 and 11/15 = 33/45
so 2 rationals between these are 31/45 and 32/45.
