EXPLANATION
In order to order the real numbers from least to greatest we need to consider that we need to draw a number line.
The line scale marks are equally spaced and usually represent integers.
To plot a real number:
Draw and label a number line
Find where the number is on the number line and place a dot on the numbers.
Plotting Real numbers on the Number Line
Example: Graph the number 3/2 and -3.5 on a number line.
Comparing Real Numbers:
In order to compare the real numbers, we need to replace the blank with > , < or = to make a true sentence.
Example:
2/7 < 0.5
3/2 > 0.5
4/4 = 1
When we are asked to order numbers from least to greatest we can use the number line to help us to plotting the numbers and reordering them.
A strategy we can use here is to convert the numbers to decimals and then plot and/or order them as requested.
