Question

решите срочно надо пожалуйста

Answer 1

(у - 8) / 11 4/7 = (8/27) / (5 1/3),

у - 8 = 11 4/7 * 8/27 : 5 1/3,

у - 8 = 81/7 * 8/27 : 16/3,

у - 8 = 81/7 * 8/27 * 3/16,

у - 8 = 9/14,

у = 9/14 + 8,

у = 8 9/14

Answer 2

$frac{ frac{y - 8}{81} }{7} = frac{ frac{ frac{8}{27} }{16} }{3} \ \ frac{7y - 56}{81} = frac{1}{18} \ \ 126y - 1008 = 81 \ \ 126y = 81 + 1008 \ \ 126y = 1089 \ \ y = frac{121}{14} = 8 frac{9}{14}$
