25×39用乘法分配侓计算? -
=1000-25 =975
=1000_25 =975
=1000-25 =975
=1000_25 =975
25x(40-1)=25x40一25 =1000一25 =975
25×3.9 =25×4-25×0.1 =100-2.5 =97.5
25乘39乖24乘法分配律简便计算怎么算 -
25x39x24 =25x39x(4x6)=(25x4)x39x6 =100x39x6 =100x(40-1)x6 =100x40x6-100x1x6 =100x240-100x6 =24000-600 =23400
25×42 =25×(40+2)=25×40+25×2 =1000+50 =1050
25×32用乘法分配律咋算 -
25×32 =25×4×8 =100×8 =800 用乘法分配律。。。很高兴为你解答,如果答案对你有帮助,请点击【选为满意答案】,O(∩_∩)O谢谢!
回答:25×(4×11) =(25×4)×11 =100×11 =1100
25x392乘法分配律怎么计算 -
392分为300和92。25乘以300加92,分配律就是25乘以300加25乘以92,结果为7500加2300等于9800,分配律就是把他拆开再算出最后结果。
原式=25x(40+1)=25x(4x10+1)=25x4x10+25x1 =100x10+25 =1000+25 =1025
