\[\frac{3(m-3)}{m(m-2)}\times \frac{(m-2)(m+2)}{(m-3)(m+2)}=\frac{3}{m}\]

thats basically what i was going to say :-D when doing problems like these, always look for things you can factor first. once you have factored what can be factored, look for like terms to cancel, then whatever is left is usually your answer

@cgian66 that looks like the same question to me. the answer is still the same. just follow the steps ive told you already, and what @Mertsj showed mathematically and you should be okay. just take it slowly and understand what has to be done...you got this!

ok that is what I was wondering , factor first then flip correct?
Mertsj
  • Mertsj
Or then flip and then factor. Makes no difference. And why did it have to be done twice?
anonymous
  • anonymous
right..well in this case @cgian66 since you have the division sign, anytime you are doing division of fractions you have to flip the second fraction then multiply. Thats why @Mertsj math shows the second fraction flipped. Then they canceled out all like terms and whatever was left was their answer.

it is not showing me the input when you type in the equation for me, says math processing error so I drew it
anonymous
  • anonymous
so i can do it before or after, makes no difference, got it, ty so much i got the cancellation part down it was just the steps agian :)

no worries @cgian66...thats why we are here :-D
