0.75÷[(0.3十2.2)x5]脱式计算

21.6÷0.8-1.2x5 =27-6 =21

=42÷42x5/7x5/7 =1x5/7x5/7 =25/49

=(48+17)X5 =65X5 =325

255十650÷13X5 =255+50×5 =255+250 =505

240÷4+62x5脱式计算 240÷4+62x5 =60+310 =370

(56+68x5)÷2-76怎样脱式计算 (56+68x5)÷2-76 =(56+340)÷2-76 =386÷2-76 =193-76 =117

(3.2+0.12)x5 =3.2x5+0.12x5 =16+0.6 =16.6

解: 原式 =20x5÷2+28÷2 =50+14 =64

32x48+32x53-32 =32×(48+53-1) =32×100 =3200

690十47X52一398脱式计算 =690+2444-398 =3134-398 =2736 98一18X5十170 =98-90+170 =8+170 =178 15X7十85X2 =105+170 =275 720÷36÷2 =20÷2 =10
