where .75 will be on a number line always varies depending on how far out your number line goes. the decimal .75 is also known as 3/4, so the easiest way to find out where 3/4 is on a number line is to divide you number line into 4 even sections. this can be difficult if you have an odd number,, but it will always work as long as you divide the length of your number line by 4 to find out where to make your even sections. below is an example on how this would work: lets say this is your number line ------------------------- that number line contains 24 dashes,, so if you take that number (which is the length of the number line) and divide it by 4 you will find where 3/4 is. 24 ÷ 4 = 6 this means that at every 6,, you add 1/4. on the number line it would look like the following: ------I------I------I------ 1/4 2/4 3/4 this technique shows you where 3/4/0.75 is on your number line. let me know if you have any further questions :)
