We have 1 over 3 plus 1 over 8 and are asked to write the result in simplified form.
00:09
So let's start by finding our lcd.
00:11
Well, let's look at both of our 5 denominators because we're going to need this to find our lcd.
00:17
Well, if we look at 3, we see this is already prime.
00:21
Well, a prime number.
00:22
So that means we just leave it alone.
00:24
But for 8, we can see that it is equal to 4 times 2.
00:30
And we see that 4 is not a prime number yet.
00:33
So we can factor it again.
00:35
Well, that's 2 times 2 times 2.
00:38
And we see that 2 is a prime number, so we'll leave it alone.
00:41
So now we need to combine these two for all of these prime numbers.
00:46
We see that 3 appears once, and that's its highest occurrence.
00:49
And 2 appears 3 times, and that's its highest occurrence...
