Our first step with any problem that subtracts or adds fractions is to look for a common denominator.
00:08
So in this case, we don't have a common denominator, which means we need to find the lowest common multiple.
00:15
This is the lowest number that they can both divide into.
00:20
So the easiest way to find this is to list some multiples.
00:23
14 has 14, 28, 42, 56, 70, etc.
00:33
35 has 35, 70, and there we go, we have a common multiple, the least common multiple.
00:43
So now that we have our number, we're going to make it the denominator of each of these fractions.
00:47
We do this by multiplying each fraction.
00:50
So 35, how do we make that 70? we multiply by 2...
