We need to convert the given rational numbers into equivalent rational numbers with same denominators.
The LCM for 5 and 4 is 20.
3/5 = 3× 20 / 5×20
= 60/100
3/4 = 3×25 / 4×25
= 75/100
Here, we now know that 61, 62, 63,..74 are integers between numerators 60 and 75.
Hence, the rational numbers between 3/5 and 3/4 are 61/100, 62/100, 63/100, …., 74/100
