Alright, here we have to evaluate 1 over 6, 1 sixth, plus 2 fifths, plus 1 third.
00:11
So what we need is what we call a common denominator.
00:15
And the way that we find a common denominator is by finding what we call the least common multiple between all of these things.
00:23
So we need the least common multiple between these different denominators.
00:31
Multiple.
00:34
So that means we need the least common multiple between 6, 5, and 3.
00:39
So if we think about the multiples of 6, it's going to be 6, 12, 18, 24, 30, 36, and so on.
00:47
If we think about 5, that's going to be 5, 10, 15, 20, 25, 30.
00:52
And then if we think about 3, that's going to be 3, 6, 9, 12, 15, 16, 18.
00:57
And so we're going to do that until we find the least common multiple, which is going to be 30.
01:02
And so now with each of these, i need to multiply them by whatever i need to in order to make the denominator 30.
01:09
So for this one, it's going to be 5, right? because 5 times 6 is 30.
01:12
So i'm going to do the top and the bottom...
