Question

10,5+1,8;67,2:12-3,25;46,2:132*1,6;(16,2,3+21,5):14;(42,3+34,2):9+3,5;(47,52-7,2):6-0,81

Answer 1

10,5+1,8=12,3
67,2:12-3,25=5,6-3,25=2,35
46,2:132•1,6=0,35•1,6=0,56
(16,2•3+21,5):14=(48,6+21,5):14=70,1:14=5,007
(42,3+34,2):9+3,5=76,5:9+3,5=8,5+3,5=12
(47,52-7,2):6-0,81=40,32:6-0,81=6,72-0,81=5,91
