1.46*4.8-4.6*0.48的简单算法

1.46*4.8-4.6*0.48的简单算法

Answer 1

1.46*4.8-4.6*0.48
=1.46*4.8-4.6*0.1*4.8
=4.8*（1.46-4.6*0.1）
=4.8*（1.46-0.46）
=4.8*1
=4.8

Answer 2

2.25*4.8+77.5*0.48=2.25*4.8+7.75*4.8=(2.25+7.75)*4.8=10*4.8=484.8*7.8+78*0.52=0.48*78+78*0.52=(0.48+0.52)*78=1*78=781.3*11.6-1.6*1.3=1.3*(11.6-1.6)=1.3*10=134.36*12.5*8=4.36*(12.5*8)=4.36*100=4362.5*32*1.25=2.5*4*8*1.25=(2.5*4)*(8*1.25)=10*10=1009.6除以3.2除以3=9.6÷(3.2*3)=9.6÷9.6=115.2除以0.25除以4=15.2÷(0.25*4)=15.2÷1=15.2
