Which ratio forms a proportion with:
\[\frac{ 27 }{ 105 }\] Simple question, It's just I forgot the rules here xD
Multiple Choice Answers Are: \[\frac{ 9 }{ 37 }\] \[\frac{ 18 }{ 70 }\] \[\frac{ 18 }{ 96 }\] \[\frac{ 18 }{ 63 }\]
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
Ah I see, thanks a bunch I had forgotten how to do this xD
it's tricky though, don't jump to conclusions after dividing, some multiplication is involved to find the right answer
Ah I see, yah I am usually thorough with my math so I hope I don't mess up lol
lemme know what u decide as your answer :)
What I don't get is that they have to be proportionate and 18 does not go into 27...
why are we talking about 18 and 27?
Well the answers all have 18 as the numerator except for A
I mean the factor I chose was 3, it fot perfectly into both.
okay so let me try to help you here :)
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?
Well thanks a bunch, I was so confused on this lol
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
But thanks so much, this will help me a lot
no problem, anytime :)
