a) (18,09:0,3-5,2X3,7):0,05=(60,3-19,24):0,05=41,06:0,05=821,2
b) 3,75X(1,7X3,4-1,7X2,3)=3,75X(5,78-3,91)=3,75X1,87=7,0125
c) 27,013-(5,73x0,2-5,73x0,1)=27,013-(1,146-0.573)=27,013-0,573=26,44
d) (2,75x100+5,4x0,02):1000=(275+0,108):1000=275,108:1000=275 108
e) (2,3x0,4+7,5x1,2-3,4x0,01)x100=(0,92+9-0.034)x100=(9,92-0.034)x100 =9.886x100=988,6
