How do I Put in order 15.25 15.03 and 15.2?

To put these numbers in order, you need to compare them digit by digit starting from the left. In this case, the numbers are all in the 15.xx range, so you first compare the tenths place. Since 15.03 is the smallest in the tenths place, it comes first. Next, compare the hundredths place, and 15.03 is still the smallest. Finally, compare the hundredths place, and 15.03 is still the smallest, so the order is 15.03, 15.2, 15.25.
