    \[\frac{ 27 }{ 105 }\] Simple question, It's just I forgot the rules here xD

    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

    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?

    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

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

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

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

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

    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?

    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?

    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.

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