Answer 1

$1)frac{1-3k}{3}:frac{18k-6}{6k} =frac{1-3k}{3}*frac{6k}{6(3k-1)}=-frac{k}{3}\2)frac{s^{2} +6s+9}{s+7}*frac{14+2s}{s+3}=frac{(s+3)^{2}}{s+7}*frac{2(7+s)}{s+3}=2s+6\(frac{q}{u^{2}})^{15}*(frac{u^{3} }{q^{4}} )^{4}=frac{q^{15} }{u^{30}}*frac{u^{12} }{q^{16} }=frac{1}{u^{18}*q}$

Answer 2

$1)frac{1-3k}{3}*frac{6k}{18k-6}=frac{1-3k}{3}*frac{-k}{1-3k}=frac{-k}{3}$

$2)frac{(s+3)^2}{s+7}frac{2(s+7)}{s+3}=2s+6;$

$3)frac{q^{15}}{u^{30}}*frac{u^{12}}{q^{16}}=frac{1}{u^{18}q}$
