500÷40的简便计算 =50÷4 =12.5

41500÷500 =41500÷(1000÷2) =41500÷1000×2 =41.5×2 =83

好孩子是不抄答案的哦!

500-(720-40x15)÷30 =500-(720-600)÷30 =500-120÷30 =500-4 =496

500÷25×4用简便运算 500÷25×4 =5*100/25*4 =5*4*4 =20*4 =80

500-(20+4X15)X10÷31 =500-80X10÷31 =500-800/31 =14700/31 =474又31分之6

应该这样算: 500÷50÷2=10÷2=5 这样简便些,而且很直观就可以出答案。

500-(720-40×15)÷30 =500-(720-600)÷30 =500-120÷30 =500-4 =496

用简便计算法来计算24×15减500除以25 24*15-500/25 =24*100+24*5-20 =2400+120-20 =2400+100 =2500
