# How To Subtract Fractions

This is a way of subtracting fractions from one another fractions with unlocked. And onliners different bottom numbers and we're going to be looking at How To Subtract Fractions how to do this pretty much. Okay, so it's without all that messy working out that you often get with fractions. And once you ‘reworking how to do this trick look it's are a great and easy method of doing it as well. Okay so what about giving you an example and I'm going to answer this one. But you see we can answer it while I'm writing it down so 3/4 take away 1/2. Now the answer that you should get with this is as follows you should get 2 over 8 look. And you can then simplify can you can simplify this further into 1/4. But only I'll leave them un simplified from the minute okay.

So, did you get that answer pretty much straight away if not I'll tell you. What I’m going to show you how to do this pretty much straight away okay and I did How To Subtract Fractions that in that exact speed. So I'll show you how to do this now as follows this is how we do it so first off. I'm going to show you how to get the bottom number they're not going to show you. How to get the top number but once you start getting used to these. I tend to start working at the top number first and then the bottom number okay. So the bottom number is pretty much easy it's our 4 times 2. Okay, so you multiply these two numbers you’re going to get your bottom number. Which is 8 okay that's the first one to get this number here this top number. What we do is as follows we're going to start and this is a critical part here. We have to start on this left-hand side and what we're going to be doing is we're in a multiplied by multiplying.

The top number on the left-hand side by this number and then this number. By this number and we're going to be taking them away from one another. So 3 times 2 How To Subtract Fractions are 61 times 4 is 4 and I'm going to 6 take away 4 to get my answer which is to Waits. And it’s critical that you actually do it in that order that you don’t go this one. By this one take away this one well this one because I was feeling that with 4 take away 6. And you get the wrong answer so we start in the top left-hand corner and we’re multiplying this way and then. This way taking answers away's a pretty easy technique. Okay anyway what about I'll give you another example here. So, it's a nice easy one what about 1/2 take away 2/5 so I'm gonna do the work. Yet with you here so let's first off get this bottom number to get that what do. Do we multiply these numbers so 2 times 5 is 10. Then what we did is we start in this top left corner 1 times 5 is 5 2 times 2 is 4.

Okay, we're taking that away so 5 takeaway 4 we get the answer of 1. So my answer is 1/10 now what I start to do after what with these is I'll start to actually How To Subtract Fractions work out this top number. First, because that's the order in which we say we say it's 1/10. So while you’re working this one out then you can work this one out for the bottom okay. So and that's the reason I'd start doing it in that order but you know whichever way. You like this I'll tell you what we'll do it one way like this now so 4/5. Where I work at the top number so 4/5 take away 2/3 and what does this equal. So this allows me to work again I'm going to show you then I'm going to start doing them in our heads. So 4 times 3 is 12 and then 2 times 5 is 10 gonna be taking that away ok. So 12 takeaway 10 it's 2 and then 5 threes of 15. So, we got 2 fifteenth’s as you go that you might want to be pausing this. While you're doing this and because you know you might take a little bit longer to start off with these.

Okay a couple more of these so what about two-thirds and from this, we're going to take away one quarter. So let's start doing this without that better working out you might pause this and do the work here. Okay you will be pausing okay but I'm going to do How To Subtract Fractions this without doing all that little working out down here. Now I’m going to start going straight to the answer so what's going on in my head. While we're doing this is eight takeaway 3 which is 5 3 times 4 is 12 how'd you go with that pretty good. Ok, last question here 4/5 take away half and once again we can start splitting this answer straight in. Because we’re going 8 take away 5 which is 3 yeah 4 times 2 is 8 take away 1 times 5. Which is 5 it's 3 and a number here and on the bottom is 2 times 5 which is 10 sorry, 10th okay pretty cool. Right, an easy method of doing these, and look you have a look at that. There's no trying to change two common denominators and all that sort of deal. You know get that bottom down with the same and there are no many lines of working out it’s pretty much there.
