Question

решите уровнение 2⅔:3⅓=х:3,5

Answer 1

2⅔:3⅓=x:3,5
8/3*3/10=x:3,5
x=3,5*4/5
x=2,8

Answer 2

$\frac{ 2\frac{2}{3} }{3 \frac{1}{3} } = \frac{x}{3.5} \\ \frac{ \frac{8}{3} }{ \frac{10}{3} } = \frac{x}{3.5} \\ \frac{8}{3} \times \frac{35}{10} = \frac{10}{3} x \\ \frac{140}{15} = \frac{10}{3} x \\ x = \frac{140}{15} \times \frac{3}{10} \\ x = \frac{14}{5} \\ x = 2 \frac{4}{5} \\ x = 2.8$
