29. 27.3-4.8=22.5
22.5*1.6=36.0
27.3+22.5+36.0=85.8


30. а) 0.64:0.8= 0.8
18.36+0.8=19.16
б) 80*11=880
42558:519=82
880-82=798
в) 3.44:0.4=8.6
8.6+24.56=33.16
г) 684*245=167.580
675*246=166.050
167.580-166.050=1.530

Answer 2

18,36+0,64÷0,8=18,36+0,8=19,16
80×11-42558÷519=880-82=798
3,44÷0,4+24,56=8,6+24,56=33,16
684×245-675×246=167580-166050=1530
