36*222 +888*16=7992+14208=22200也可以222x100=22200

解:这种题都要变一下36X222十888X16=36X222+222X4X16=222X36+222X64=222(36+64)=222X100=22200

36/222 888/91的简便算式36/222 888/91=9*4*222+888*91=888*(9+91)=888*100=88800

36x222+888x16=36x222+222x64=(36+64)x222=100x222=22200

36剩以222+888乘以91的简便运算36剩以222+888乘以91=222*4*9+888*91=888*(9+91)=888*100=88800

37*222+888*4=37*222+222*4*4=37*222+222*16=222*(37+16)=222*53=222*(50+3)=11100+666=11766

1/3+3/4+2/5+5/7+7/8+9/20+10/21+11/24+19/35 =(1/3+3/4+7/8+11/24)+(2/5+9/20)+(5/7+10/21+19/35) =(8/24+18/24+21/24+11/24)+(8/20+9/20)+(75/105+50/105+57/105) =29/12+17/20+26/15 =145/60+51/60+104/60 =300/60 =5

888*36+222*56=111*8*36+111*2*56=111*4*(2*36+28)=444*100=44400 不懂再问哦

666*12+888*16=222*(3*12)+222*(4*16)=222*36+222*64=222*(36+64)=222*100=22200
