Find a common denominator, the easiest way to find one is to multiply all the denominators together.
Can you finish it from here?
Well lets take the first term as a case study.
As you understand we need to make the denominator 13 into 442. This is done by multiplying by 17 and 2. I.e 13 by 17 by 2 = 442.
So if we are changing the demoninator by multiplying by 17 and 2, then we must also do this to the numerator.
Now you need to do this to the 2nd and 3rd term.
You multiplied all the denominators together to get the final denominator.
So what is left is to multiply the numerator correct?
What the question i am referring to is the numerator, I can't get a grasp on why your multiplying. Sorry if I'm asking so many questions' but i am using this to write a study guide for myself, since i am home schooling. That is why i asked if their are tutorials on problems such as the one i presented with a in depth write up.
