1. The problem is to arrange the numbers 14.7, 14.71, and 14.70 in ascending order. 2. To compare decimal numbers, we look at the digits from left to right, starting with the whole number part, then the tenths, hundredths, and so on. 3. All numbers have the whole number part 14. 4. Compare the tenths place: - 14.7 has 7 in the tenths place. - 14.71 has 7 in the tenths place. - 14.70 has 7 in the tenths place. 5. Since the tenths are equal, compare the hundredths place: - 14.7 can be considered as 14.70 (adding a zero does not change the value). - 14.71 has 1 in the hundredths place. - 14.70 has 0 in the hundredths place. 6. Now, order by hundredths: - 14.70 (0 hundredths) < 14.7 (equivalent to 14.70) < 14.71 (1 hundredth) 7. Therefore, the ascending order is: $$14.7 = 14.70 < 14.71$$
