Order numbers from least to greatest 15.142 15.41 1.547 5.4 51.4 I'm having such a hard time with these.

Try it this way ... if there is empty spaces after the decimals or before, add 0's to make them the same length ... that doesn't sound right ... let me just show u ... oh, and make sure ur decimals line up

15.142

15.410

01.547

05.400

51.400

now, least to greatest : 1.547, 5.4, 15.142, 15.41, 51.4
