The question:

PUT IN ORDER FROM LEAST TO GREASTEST

A. 2.17
B. 2.017
C. 20.17
D. .2017



The answer:

Ordinarily, I would recommend you try to visualize these numbers on a number line.

However, the decimal differences are so close, I recommend you start your comparison by lining up the decimals in a vertical column (straight up and down). I’m going to use the 0 sign as a spacer.


02.17
02.017
20.17
00.2017


Now, add 0’s so that each of the numbers has a decimal with the same number of decimal places (in this case, 4 decimal places).

02.1700
02.0170
20.1700
00.2017

At this point, rewrite the numbers without the decimals.

021700
020170
201700
002017

Because there are no decimals to complicate the comparison, lining up the numbers from least to greatest is easy (add commas as a grouping symbol to make it even easier).

Sorted least to greatest

002,017
020,170
021,700
201,700



To return the numbers to their original format, remove the commas, and put the decimal points back in the numbers

00.2017
02.0170
02.1700
20.1700

Remove the extra zeros

.2017
2.017
2.17
20.17

Your final answer is (numbers sorted from least to greatest):

D .2017
B 2.017
A 2.17
C 20.17



Thanks for writing.
