tell rational no between -2/3 and4/5
topsnooper:
2÷3 = (2×40)÷(3×40) = 80÷120. 4÷5 = (4×24)÷(5×24) = 96÷120. Therefore rational numbers between 80/120 and 96/120 = 81/120, 82/120, 83/120, 90/120, 91/120.

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 66/90 67 /90 .....
(sorry by mistake, I found 5 rational number)
