你好,同学,麻烦把原题的截图发出来,这样能够快速有效地解决问题
答案7.5,计算过程:5.6x3/4+3.4x75%+0.75=5.6x0.75+3.4x0.75+0.75 =0.75x(5.6+4.3+1) =0.75x10=7.5运用乘法分配律的方逆运算
答案7.5,计算过程:5.6x3/4+3.4x75%+0.75=5.6x0.75+3.4x0.75+0.75 =0.75x(5.6+4.3+1) =0.75x10=7.5运用乘法分配律的方逆运算
5.6x3/4+3.4x75%+0.75 =5.6x0.75+3.4x0.75+0.75 =0.75x(5.6+3.4+1) =0.75x10 =7.5
乘法分配律的逆运算axb+axc+axd=ax(b+c+d)
3/4=0.75 75%=0.75
