Which decimal is less than 1 and greater than 0?
Answer and explanation
Correct answer: 0.89
The governing concept is comparison of decimal numbers using their whole-number parts and, when necessary, decimal digits. A number greater than 0 but less than 1 must have whole-number part 0 and a positive fractional part. Among the choices, 0.89 satisfies both conditions: 0 < 0.89 < 1. Therefore option B is correct. The number 1.25 is greater than 1, 1.00 is exactly equal to 1 rather than less than 1, and 2.09 is also greater than 1. A quick checking method is to inspect the digit before the decimal point: a positive decimal between zero and one begins with 0, while a number beginning with 1 or 2 is at least 1.
