Is going to make four pans of fudge, and that each pan needs two -thirds a cup of condensed milk.
00:06
So in part a, what we need to determine is how much condensed milk that she's going to use.
00:12
Well, if you think about it, she has these four pans, so one, two, three, four, and each of the pans is going to use two -thirds cups.
00:23
So this pan would use two -thirds, this one would have two -thirds, and this one would have two -thirds.
00:28
So if we need to figure out the total amount, we just need to multiply 4 by 2 thirds.
00:35
Well, remember, to multiply fractions, we multiply straight across.
00:38
So to make 4 into a fraction, i can put it over 1.
00:42
And then again, we're going to go straight across.
00:44
Well, 4 times 2 is equal to 8, and 1 times 3 is equal to 3.
00:49
So now we have our answer as an improper fraction.
00:52
They also want us to write this as a mixed number.
00:55
So remember, to do that, we need to divide the numerator by the denominator.
00:59
Well, three goes into eight two times, two times three is six, and eight minus six is two.
01:05
So two is our remainder.
01:07
So it goes in two whole times, and then there's two remaining out of the three...
