125x30x24的脱式计算怎么写?

125x30x24 =125x30x(8*3) =125*8*3*30 =1000*90 =90000

125×32—125×24 =125×(32—24) =125×8 =1000

326×24 =325×24+24 =﹙200+125﹚×8×3+24 =4800+3000+24 =7824

=728-(34+600) =728-(28+6+600) =728-28-6-600 =700-600-6 =100-6 =94

99x24/25 =(100-1)×24/25 =100×24/25-24/25 =96-24/25 =95又1/25

解:54+88*24 =54+2112 =2166

41600÷128x24 =325×24 =7800

=387(24+75+1) =387*100 =38700

50-50x24÷80 =50-1200÷80 =50-15 =35

36x24+12x24+48 =(36+12)x24+48 =48x24+48 =48x(24+1) =48x25 =1200
