So we're adding together two fractions, which means we need a common denominator.
00:06
So the first thing we're going to do is find the least common multiple between 3 and 2, since these are our two denominators.
00:15
The least common multiple is the smallest number that both of these numbers can divide into.
00:21
A good way to find these is to just list some multiples.
00:24
So 3 times 1 is 3, 3 times 2 is 6, 3 times 3 is 9, and for the 2.
00:30
2, we have 2 times 1 is 2, 2 times 2 is 4, 2 times 3 is 6, and we look for which ones they have in common, which already we find 1, 6.
00:41
They both have 6, and that is the smallest number they have in common.
00:46
So now we're going to transform each of these fractions, so they have a denominator of 6.
00:52
So we do that by multiplying the fractions by a number that will make the denominator 6...
