Find out how much total medicine we need.
00:03
Well, we have three halves, milliliters, and then two -thirds milliliters, and one -fourth milliliters.
00:09
So we're adding three - halves plus two -thirds plus one -fourth.
00:13
We need to have a common denominator of it looks like 12 here.
00:17
So our first fraction, three - halves, we're going to multiply by six over six to get a denominator of 12, which, again, is the same thing as multiplying by one, right? so 6 over 6, or 1 times 3 halves, is going to be, well, 6 times 3 is 18.
00:34
So we have 18 twelfths, it's 3 halves, and then plus 2 thirds, well, that's going to be multiplied by 4 over 4.
00:45
So 4 times 2 is 8.
00:47
So we have 1812s plus 8 twelfth, and then plus 1 4th is going to be multiplied by 3 over 3...
