Question

are terminating decimals rational numbers

Answer 1

No, terminating decimals are not rational numbers. Rational numbers can be written as a fraction and have a finite or repeating decimal representation. Terminating decimals have a finite number of digits after the decimal point, but they can still be written as a fraction with a denominator that is a power of 10. For example, 0.5 is a terminating decimal and can be written as 1/2, which is a fraction. Therefore, terminating decimals are rational numbers.
