原式=4.6÷0.25=4.6x4=4x4+0.6x4=16+2.4=18.4 供参考.

4.6÷4÷0.25=4.6*1/4÷(1/4)=4.6*1/4*4=4.6

14.75除4除0.25 =14.75÷(4*0.25) =14.75÷1 =14.75

4.6乘0.25的简便运算,4.6x0.25=(4+0.6)x0.25=4x0.25+0.6x0.25=1+0.15=1.15希望能帮到你

=4.5*4=18

4.6/0.25=4.6*4 因为0.25=1/4.所以4.6/0.25=4.6/(1/4)=4.6*4.

25*9 =25x(100-1) =25x100-25 =2500-25 =2475 (25+60)*4 =25x4+60x4 =100+240 =340

=(0.25x4)x(0.2x4.6)=1x0.92=0.92

4x2.5x0.25=10x0.25=2.5也可以这样做:4x2.5x0.25=4x0.25x2.5=1x2.5=2.5

4.6÷0.25=(4.6*4)÷(0.25*4)=18.4÷1=18.4
