How To Add Fractions 4th Grade

- what i want to do in this video is compare the fraction7/10 to the fraction 8/9. and, like always, i encourageyou to pause the video and see if you can figureout where these things-- one of these is larger than the other,

How To Add Fractions 4th Grade, or whether they are equal. so, for me in this video, iwant to think about it visually. and i'm going to do thatusing wholes of the same size that are circles.

so let me draw them orlet me get them, here. so there you go, so theseare wholes of the same size. i'm gonna compare 7/10 ofthis whole of the circle to 8/9 or this whole. which is a circle of the exact same size. if you're comparing 7/10 of a small circle to 8/9 of a bigger circleor 7/10 of a big circle to 8/9 of a smaller circleor a different shape, then you really can't make the comparison.

but we're gonna compare7/10 of the same whole to 8/9 of the same whole. now, you can see the waythat i've pre-drawn it. the circles are the same size, but i have divided them into adifferent number of sections. here, since i have10ths, i've divided into, you see that i've divided itinto, one, two, three, four, five, six, seven, eight,nine, ten sections. over here, since we're dealing with 9ths,

you can see i've dividedit into one, two, three, four, five, six, seven,eight, nine sections. but let's think aboutwhat 7/10 represents. it represents 7 of these 10 sections. so let me color them in. let me get my coloring in tool. so that represents one, two, three four, five, six, seven out of the ten sections. now what about 8/9?

8/9 is going to represent 8of these 9 equal sections. one, two, three, four, five, six, seven, eight of those sections. so which one of these is larger? which one is larger? well you can see very clearly, remember we're using 8/9 of the same whole and 7/10 of that exact same whole. you see that we havecolored in more in magenta,

or this pinkish colorthan we have in blue. so 8/9 is the larger of these two. or we could say that7/10 is less than 8/9. and once again, the way iremember what symbol to use, we always want it opening to the larger of the two number or the little, the tip is going to be pointing to the smaller of the two number. so, 7/10 is less than 8/9.
