Question
4. What is the difference between terminating and repeating decimals? How does the end behavior of a decimal relate to rational number or irrational number?

Terminating decimals are decimal numbers that have a finite number of digits after the decimal point, meaning they end after a certain point. For example, 0.25, 1.75, and 3.0 are terminating decimals. On the other hand, repeating decimals have a pattern that repeats indefinitely after the decimal point. For example, 0.333..., 1.666..., and 1.272727... are repeating decimals.
The end behavior of a decimal can provide information about whether it represents a rational number or an irrational number. A rational number is a number that can be expressed as a fraction (or ratio) of two integers, and its decimal representation either terminates or repeats. Therefore, any decimal number that terminates or repeats is a rational number. In contrast, an irrational number cannot be expressed as a fraction of two integers, and its decimal representation neither terminates nor repeats. Irrational numbers have an unpredictable and non-repeating pattern of digits after the decimal point.
In conclusion, the difference between terminating and repeating decimals lies in their patterns after the decimal point. The end behavior of a decimal can help determine whether the number is rational (terminating or repeating) or irrational (neither terminating nor repeating).
