(165,6-121):(42,12+180,88)=44,6:223=0.2

d)(72,4×2.75+0.9):(57,4:16,4-7,4)=

(199.1+0.9):(3,5-7,4)=

200:(-3,9)=-51,28

b)3,4×[0.5×(21.4×6.5-39.7)-21.5]=

2,4×[0.5×(139.1-39.7)-21,5]=

2,4×(0.5×99.4-21,5)=

2,4×(49.7-21,5)=

2,4×28,2=67,68

d)0.5×[2,4×(23,4×3.5-37.4)-6,4]=

0.5×[2,4×(81.9-37,4)-6,4]=

0.5×(2,4×44,5-6,4)=

0.5×106.8-6,4=
