Пошаговое объяснение:
1) 1 1/9:x=2 2/3:3 3/5;
x=1 1/9 * 3 3/5 / 2 2/3;
x=(10/9*18/5) / (8/3);
x=3/2 = 1.5.
-------------
2) 1.25/(y+2) = 0.6/2.4;
y+2=1.25*2.4/0.6;
y+2=5;
y=3.
--------------
3) 6x:3 1/3 = 2.4:1/12;
6x=3 1/3*2.4:1/12;
6x=96;
x=16.
----------------
4) 4 1/2:0.6=(4y-2)/4/9;
4y-2=4 1/2 * 4/9 : 0.6;
4y-2=10/3;
4y=10/3+2;
y=4/3=1 1/3.
