Draw a number line from 0 to 2 write 3\8 1 and 3\4 and 1.25 on the number line,

To solve this exercise you must apply the proccedure shown below:
 1- You have the following numbers given in the problem above:
 3/81, 3/4 and 1.25
 2- Therefore, you have that 3/81 in decimal form, is: 
 3/81=0.03
 3- 3/4 in decimal form is:
 3/4=0.75
 3- Keeping this on mind,  you can draw the number line from 0 to 2 and write the numbers given above, as you can see in the figure attached.

The graph of the number line from 0 to 2 is shown in Figure 1. We start this graph by setting the number zero to the left of the number 2, that is, the numbers increases from left to right. Next, we have the following points to be marked in the number line:

 

But we can rewrite these numbers as decimals:



So Figure 2 shows each point marked on the number line. The way we choose is to set each point on the number line analyzing in which position it must lay. For instance, is less than but greater than zero. So its position is as indicated in Figure 2.
