Okay, so we're adding one -third plus five twelfths plus four -fifths.
00:06
It looks like our common denominator here is going to be 60.
00:13
So we can multiply, well, three times 20 is 60, so one times 20 is well 20, right? multiplying one -third by all 20 over 20, which is the same thing as multiplying by 1.
00:26
