Question 406706: I have worked this out but am not sure if it is right. Would you please check it?
(fractions)
(3)/(4)n-(1)/(12)n = 6
(3n)/(4)-(1n)/12) = 6
(12(3n)-4n)/(12)
(36n-4n)/(12)
(32n)/(12)=32 muliply both sides by 12
(32n)/(32n) = (384)/(32)
n = 12

Hi

%283%29%2F%284%29n-%281%29%2F%2812%29n+=+6

%289%29%2F%2812%29n-%281%29%2F%2812%29n+=+6

%288%29%2F%2812%29n+=+6

%288%29=+6%2812n%29

%288%2F72%29=+n  n = 1/9

CHECKING our Answer***

 3 /4/9 - 1/12/9 = 6

  3*9/4 - 9/12 = 6

    27/4 - 3/4 = 24/4 = 6
