12x36十36x28 =36×(12+28) =36×40 =1440

原式 =36*1/6+36*1/12-36*1/18 =6+3-2 =7 满意采纳奥

102X36+12X24 =102X36+12X3X8 =102X36+36X8 =(102+8)X36 =(100+10)X36 =100x36+10x36 =3600+360 =3960

(一4分之三一9分之五十十二分之七)x负三十六 =3/4x36+5/9x36-7/12x36 =27+20-21 =26

5.63x6.34+0.563x36.6 =5.63×6.34+5.63×3.66 =5.63×(6.34+3.66) =5.63×10 =56.3 1240x3.8+124x63-12.4x10 =124×38+124×63-124 =124×(38+63-1) =124×100 =12400
