order the numbers from least to greatest

A number line is a faster, more efficient way of calculating whole numbers, and only takes a few seconds, a lot faster than mental calculation.
because the # line shows the rational #'s in order from least to greatest
To order fractions and decimals, you can either write them all in the same form and then compare them, or place them on a number line. Recall that numbers increase in value as you move from left to right along a number line.
This means:Draw a number line with some numbers labelled on it.Place dots on the number line where the rational numbers to be compared lie.State how the numbers compare in size with one another.There are various ways of doing this; here are two:1/2 is less than 5/41/2 < 5/4
Since the numbers on a number line increase from left to right, it follows that any number to the left of another number is smaller than that other number. Of course, most of the time it is quite obvious which of two numbers is larger, and we don't need to plot them on a number line to find that out.
