Answer:
D. a rational number and a terminating decimal.
The number 1.381432 is a rational number and a non-repeating decimal. A rational number is a number that can be expressed as a ratio of two integers. In this case, 1.381432 can be expressed as the ratio of 1381432/1000000, which can be simplified to 689/500. It is also a non-repeating decimal, meaning that the decimal digits do not repeat in a pattern, but rather continue on without repetition. Therefore, the correct answer is not option C, which suggests that a number is a rational number and a repeating decimal.
