How To Add Algebraic Fractions Youtube

we're asked to select whichfractions add together to make 25 over 22, or 25/22. you can use as manyfractions as you need. put all unused fractionsinto the trash can. so let's think abouthow we could do this.

How To Add Algebraic Fractions Youtube, so i actually want to usethe largest fraction first, just so i can get pretty close. so i'm going to make 16/22. and let's see, ifi add 8/22 to that,

then that's going to get meto--let's see, 16 plus 8, that gets me to 24/22. this is 16/22 plus 8/22is going to get me 24/22. and if i get one more,that gets me to 25/22. and then i could put theseunused ones down here in the trash can. so i'm going to put theseunused ones down here. and let's actuallycheck our answer. got it right.

and there's multipleways that we could have actually done this. actually, it's not clearthat there's multiple ways that we could have done this. let's see-- isthere any other way? yeah, because even if wedid the 2 and the 4 here, we would have to get to-- let'ssee, 8 would get us to-- this is 2/22 plus 4/22is 6/22, plus 8/22 is going to be 14/22, yeah.

and then if you put 16/22,there's going to be too many. so actually, the waywe did it was the way that you've got to do it. so the 2 and the 4 i'm goingto put in the trash can. and 16 of something plus 1 ofsomething plus 8 of something is going to be 25of that something. and in this case, the somethingthat we're talking about are 22nds.
