All right, on this problem, my goal is to take the fraction 18 over 90 and put it in simplest form or lowest terms.
00:07
It means the same thing.
00:10
All right.
00:11
So the first thing i need to do is to figure out the greatest common factor between 18 and 90.
00:18
So i'm going to list the factors of 18.
00:19
What can i multiply to get 18? i could do 1 times 18.
00:27
I could do 2 times 9.
00:29
So i'm going to go two times nine.
00:33
I could do three times six.
00:41
I think that's it for 18.
00:43
Now i'm going to list the factors of 90.
00:46
So i could do one times 90.
00:51
I could do two times 45...
