a)0,15 x 1,2+6,25:2,5=0,18+6,25:2,5=0,18+2,5=2,68
b)17,57-0,2 x 3+1,44:1,2=17,57-0,6+1,2=18,17
c)3,5+10³ x (0,3)³-79,8:4,2=3,5+(10 x 0,3)³-19=3,4+3³-19=3,5+27-19=30,5-19=11,5
d)48:0,2+3,2²:1,6-4,3 x 0,1=240+(16/5)³:(8/5)-0,43=240+256/25 x 5/8-43/100=240+32/25 x 5-43/100=(240) x 100+(32/5) x 20-43/100=24000+640-43/100=24597/100=245,97
