Question

помогите решить уравнение !!!!!!!!!!
11_1/5:7=10_1/2:x

Answer 1

11 1/5 : 7 = 10 1/2 : Х
56/5 : 7 = 21/2 : Х 
56/35 = 21 / 2Х 
56 * 2X = 35 * 21 
112X = 735 
X = 735 : 112 
X = 6,5625

Answer 2

$11 frac{1}{5} :7=10 frac{1}{2} :x \ \ frac{11 frac{1}{5} }{7} = frac{10 frac{1}{2} }{x} \ 7*10 frac{1}{2} =11 frac{1}{5} *x \ \ 7*10 frac{2}{10} =11 frac{2}{10}*x \ \ 7*10.2=11.2*x \ 11.2x=7*10.2 \ 11.2x=71.4 \ x=71.4/11.2 \ x=6.375$
