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

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