Пошаговое объяснение:
1) 0.21х = 6.3, х = 6.3 : 0.21, х = 30
4) 0.132х = 132, х = 132 : 0.132, х = 1000
7) 13.5х = 1.08, х = 1.08 : 13.5, х = 0.08
10) 0.32х = 16.48, х = 16.48 : 0.32, х = 51.5
2) 0.04х = 2, х = 2 : 0.04, х = 50
3) 2.7х = 2.727, х = 2.727 : 2.7, х = 1.01
5) 0.6х = 4.2, х = 4.2 : 0.6, х = 7
6) 17.5х = 0.63, х = 0.63 : 17.5, х = 0.036
8) 0.34х = 10.54, х = 10.54 : 0.34, х = 31
9) 0.09х = 94.5, х = 94.5 : 0.09, х = 1050
11) 0.35х = 2597, х = 2597 : 0.35, х = 7420
12) 1.2х = 4.02, х = 4.02 : 1.2, х = 3,5
