So the first thing we're going to do is find a common denominator for these two fractions.
00:06
So we're going to do this by determining the least common multiple of 18 and 12.
00:13
So let's start by listing some multiples.
00:16
For 18, we have 18, 36.
00:20
For 12, we have 12, 24, 36.
00:25
So i stopped here because we have a common multiple already, 36.
00:31
And this is the smallest number that they can both multiply 2.
00:34
Now that we have our least common multiple, we're going to multiply each of these fractions so that they can have a denominator of 36.
00:42
So for 5, we're going to multiply by 2 over 2, so that 18 times 2 can become 36...
