Question

Quizplus · Accepted Answer

Starting with the smallest digit to the right, we see that the digits in the first decimal place are all different. Therefore, we can order these numbers directly without having to compare any other digits. So, we start with 1.09 and 1.099, then move on to 1.9 and 1.999. The correct order is: 1.09, 1.099, 1.9, 1.999. Hence, the best choice is B. We can arrange the numbers in order by looking at the digits after the decimal point. Starting with the smallest decimal, we have 1.09, 1.099, 1.9, and 1.999. So, the correct order is 1.09, 1.099, 1.9, and 1.999, which is presented in choice B.
