(4,2:0,012+3,5×0,24)×1,7

=(350+0,84)×1,7=

=350,84×1,7=

=596,428

b)

(0,1×0,02+7,3×1,5-1,3×2,1)×100

=(0,002+10,95-2,73)×100=

=(10,952-2,73)×100=

=8,222×100=

=822,2

c)

(3,5×2,4-1,2:0,4-5×0,01)×10=

=(0,4-3-0,05)×10=

=5,35×10=

=53,5

d)

1,03×(4,5÷0,4+3,5÷0,2-0,7×0,1)=

=1,03×(11,25+17,4-0,07)=

=1,03×28,68=

=29,5404

e)

0,1×{3+3,2×[100×0,01+5,2×(4-1,2×0,1)]}=

=0,1×{3+3,2×[1+5,2×(4-0,12)]}=

=0,1×[3+3,2×(1+5,2×3,88)]=

=0,1×[3+3,2×(1+20,176)]=

=0,1×(3+3,2×21,176)=

=0,1×(3+67,7632)=

=0,1×70,7632=

=7,07632
