Use parentheses: (x + 6)/(a million-x) / (x^2 - 9x + 18)/(x^2 - 7x + 6) = ((x +6)(x^2 - 7x + 6))/((a million - x)(x^2 - 9x + 18)) = ((x + 6)(x - 6)(x - a million))/((a million - x)(x - 6)(x - 3)) = ((x + 6)(x - 6)(-a million)(a million - x))/((a million - x)(x - 6)(x - 3)) = (-a million)(x + 6)/(x - 3) = (-x - 6)/(x - 3)
(9x - 9)/11 ÷ (3x - 3)/44
= [9(x - 1)]/11 * [4(11)]/[3(x - 1)]
= 9/11 * [4(11)]/3
= 9 * 4/3
= 3 * 4
= 12
9x-9/11 divided by 3x-3/44
= (9(x -1/11)) / (3(x - 1/44))
= 3(x-1/11) / (x - 1/44)
= 3(44x - 4) / (44x - 1)
= 12(11x - 1) / (44x - 1)
