To compare decimals, fractions, and mixed numbers on a number line, you should locate each number or fraction one by one on a number line. Next, you need to determine which numbers are the greatest and which numbers are the least. Remember that greater values are always to the right, and the least values are to the left.
You can identify the number with the least value by determining which plotted number is farthest to the left.
Hope this helps! :)
