How many decimals places does an rational number have

1 answer

A rational number can have a finite number of decimals or an infinite number of repeating decimals. For instance, 1/2 can be written as 0.5, which has one decimal place, while 1/3 can be written as 0.33333..., which has an infinite number of repeating decimals. Therefore, the number of decimal places for a rational number can vary.
