We are told that a person has 29 and a half yards of material to make doll outfits.
00:09
Each outfit takes three quarters of a yard or three fourths.
00:22
We want to know how many outfits we can make and how much material is left over.
00:28
Well, if we had 30 yards of material and each one took two yards, then the way we would find the number of outfits made would be to take the 30 yards divided by the two yards per outfit.
00:41
Here we have 29 and a half yards, each one needing three -fourths yards.
00:48
So we want to divide 29 and a half by three -fourths.
00:55
Now we do need to change those into to fractions.
01:00
To get 29 and one half as a fraction, we take on the top 29 times 2 plus 1.
01:10
We keep the denominator.
01:12
It's top times, or should be integer times bottom plus the top.
01:20
And we're 59 over 2 divided by 3 over 4.
01:29
To divide by a fraction, you can change it to multiplication by flipping over what we're dividing by.
01:42
So instead of putting divided by 3 fourths, let's put plus plus 4 thirds.
01:49
We can reduce a little bit before we finish that.
01:54
2 and 4, well, 2 goes into both.
01:58
2 into 2 once, into 59 twice.
02:01
So we have 118 over 3...
