A decimal form of an rational number is

Answer 1

A rational number can be expressed in decimal form in two main ways: as a terminating decimal or as a repeating decimal.

1. Terminating Decimal: A rational number has a decimal representation that ends after a certain number of digits. For example, the fraction $\frac{1}{4}$ equals 0.25, which terminates after two decimal places.

2. Repeating Decimal: A rational number can also have a decimal representation that continues indefinitely with a repeating sequence of digits. For instance, the fraction $\frac{1}{3}$ equals 0.333..., where the digit 3 repeats infinitely.

In summary, the decimal form of a rational number can be either terminating or repeating, but it will never be non-repeating and non-terminating. This is a defining property of rational numbers.
