Question

Quizplus · Accepted Answer

When comparing decimals, it is best to start from the leftmost digit and compare each subsequent digit until a difference is found. The leftmost digit in all three numbers is 0, so we move to the next digit. In 0.21 and 0.219, the next digit is 2, while in 0.205, it is 0. Since 2 is greater than 0, 0.205 is the smallest number. Moving on to the next digit, in 0.21, the third digit is 1, while in 0.219, it is 9. Since 9 is greater than 1, 0.219 is the largest number, and 0.21 is in between, so the correct order is 0.205, 0.21, 0.219. Therefore, the best choice is C.
