well find the common factor and cancel out, i would start with 2, if 2 doesn't factor out of both, then i'll move on to 3, until i find a common factor

4. JA1 Group Title

Ok got it, and so my objective would be to make sure that both the numerator and the denominator are divided by the same number?

5. sasogeek Group Title

yes, and once u do that, find out what the result of both the numerator and denominator are when u divide them, the answer will come smiling at you :) trust me

6. JA1 Group Title

Ah I see, thanks a bunch I had forgotten how to do this xD

7. sasogeek Group Title

it's tricky though, don't jump to conclusions after dividing, some multiplication is involved to find the right answer

8. JA1 Group Title

Ah I see, yah I am usually thorough with my math so I hope I don't mess up lol

9. sasogeek Group Title

lemme know what u decide as your answer :)

10. JA1 Group Title

Hmm....

11. JA1 Group Title

What I don't get is that they have to be proportionate and 18 does not go into 27...

12. sasogeek Group Title

why are we talking about 18 and 27?

13. sasogeek Group Title

what did u do?

14. JA1 Group Title

Well the answers all have 18 as the numerator except for A

15. JA1 Group Title

I mean the factor I chose was 3, it fot perfectly into both.

16. sasogeek Group Title

Ok so I had gotten as far as getting 9/35 but I had no clue about the second part...

19. sasogeek Group Title

divide both numbers by 3 and you get 9/35, multiply both numbers by 2 and u have your answer :) i figured you had an idea when u mentioned 18, idk how u got 27 though lol, what did u do exactly?

20. JA1 Group Title

Well I saw that both 105 and 27 had a common factor of 3 so I divided by that, but I didn't know you had to multiply afterwards I was confused because all the other answers didn't go into 27 (18) so I was confused lol but I get it now, btw do you always multiply by 2?

22. JA1 Group Title

Ohhhhhh ok I get it now

23. JA1 Group Title

Well thanks a bunch, I was so confused on this lol

24. sasogeek Group Title

you don't always multiply by 2, if you don't find your answer after dividing, find a number that if you multiply by both numerator and denominator, you'll get the desired result. it doesn't have to always be 2. because really, any number divided by itself is 1.

25. JA1 Group Title

yah you cleared that confusion up when you mentioned how 2/2 is actually just 1

26. JA1 Group Title

But thanks so much, this will help me a lot

27. sasogeek Group Title

no problem, anytime :)
