Question

Which of the following numbers has a decimal which terminates?

(a) 3
(b) 9
(c) 0.3
(d) 2

Answer 1

All the given numbers (3, 9, 0.3, and 2) have terminating decimals because they can be expressed with a finite number of digits after the decimal point.

Step-by-step explanation:

The question asks which of the following numbers has a decimal which terminates: (a) 3 (b) 9 (c) 0.3 (d) 2. When we discuss terminating decimals, we refer to a decimal number that has a finite number of digits after the decimal point. Among the options given:

• (a) 3 is a whole number and thus its decimal representation is 3.0, which is a terminating decimal.
• (b) 9, similarly, is a whole number and can be expressed as 9.0, also a terminating decimal.
• (c) 0.3 is a decimal number that clearly has one digit after the decimal point, which makes it a terminating decimal.
• (d) 2 is another whole number that as a decimal is 2.0, which is again a terminating decimal.

Therefore, all the given options (a) 3, (b) 9, (c) 0.3, and (d) 2 have terminating decimals.
