All right, so this problem is telling me that there's this chef who has 15 and a half cups of sugar, right? and he knows that to make one cake, it will take him take one and three fourths cups of sugar.
00:14
And he's trying to figure out how many cakes can he make? okay.
00:17
So again, this is a division problem.
00:19
Basically, we're going to do 15 and a half, divide that by one and three fourth.
00:26
So the first thing i need to do is i need to change these into improper fractions.
00:30
Okay.
00:30
So if the denominator is 2, it's going to stay 2.
00:36
2 times 15 is 30, plus 1 more is 31, divided by here my denominator is 4.
00:47
So it's going to stay 4.
00:48
So 4 times 1 is 4 plus 3 more is 7.
00:53
All right.
00:54
Next, when i want to solve a division problem with fractions, the rule is i'm going to leave the first fraction alone.
01:04
I'm changing this to multiplication.
01:06
And i'm going to take the reciprocal of this one.
01:09
That means i'm just going to flip it over...
