Hi my name is Marija. I'm a mathematician and today I'm going to show you how to put decimals into a graph. So if we have a number line and we needed to graph something like let's say X is greater than 3.5, okay, what you do on your number line is you look at the whole number part of the decimal and it's going to lie, your number is going to lie between this number and the following number. So that means that I'm just going to be plotting a number between 3 and 4. So I go to 3 and I go to 4 and because it's .5 that means that it's going to lie exactly in the middle of 3 and 4. So 3.5 would graph right there. So if I wanted to graph X is greater than 3.5, I would put an open circle on 3.5 which is between 3 and 4 and go ahead and graph to the right. Now a number like .7 that doesn't have a number before the decimal, I have to remember that not having a number there is the same thing as having a 0 there. So this number would be graphed between 0 and 1. So .7 is going to fall somewhere right here, okay? So if there is a whole number before it, you're going to go between that number and the following one and if there is no number before the decimal, you're going between 0 and 1. My name is Marija and I just showed you how to graph decimals.
