Ответ:

Пошаговое объяснение:

1) $1\frac{1}{9}:x=2\frac{2}{3}:3\frac{3}{5} \\1\frac{1}{9}*3\frac{3}{5}=2\frac{2}{3}x\\\frac{10}{9}*\frac{18}{5}=\frac{8}{3}x\\\frac{8}{3}x=4\\x=4:\frac{8}{3}\\x=4*\frac{3}{8}\\x=\frac{3}{2}\\x=1,5$

2) $\frac{1,25}{y+2}=\frac{0,6}{2,4}\\(y+2)*0,6=1,25*2,4\\(y+2)*0,6=3\\y+2=3:0,6\\y+2=5\\y=5-2\\y=3$

3) $6x:3\frac{1}{3}=2,4:\frac{1}{12}\\6x*\frac{1}{12}=2,4*3\frac{1}{3}\\\frac{x}{2}=\frac{24*10}{10*3}\\\frac{x}{2}=8\\x=8*2\\x=16$
