b)(3,27+0,73)*0,31=4*0,31=1,24

c) 17,2*(135,8-72,75)=17,2*63,05=1084,46
d)(10,025-4,975)*5,2=5,053*5,2=26,2756

e) (17,5-5,5)(3,75-2,95)=12*0,8=9,6

f)52-25*(14,175-12,125)=52-25*2,05=52-51,25=0,75

g)10*14,3-100*0,127=143-127=16

h)(7,47-4,97)*10+12,7*1,2=2,5*10+15,24=25+15,24=40,24

I) (137,5-117,3)*(12,7-11,2)=20,2*1,5=30,3

j)(0,71-0,52)(14,3+12,5)*10²=0,19*26,8*100=19*26,8=509,2
