48 0.48x0.5 简便运算

0.48x99+0.48=0.48x(99+1)=0.48x100=48 祝天天向上.

1.25x0.48x0.5怎么简便=1.25x0.8x(6x0.5)=1x3=3

0.78-0.24=0.54

你好!0.48 x 100.1 = 0.48 x(100+0.1) = 0.48 x 100 +0.48 x0.1 = 48 + 0.048 = 48.048如果对你有帮助,望采纳.

2.4/0.48/0.5= 2.4/(0.48x0.5)= 2.4/0.24= 10

48/0.56+44/0.48=1006*8/+4*11/ =1006/7+11/12=100*149/84=25*149/21=3725/21=177又8/21

48*0.56+44*0.48=0.48*56+44*0.48=0.48*(56+44)=0.48*100=48

原式=48x0.56+0.44x100x0.48=48x0.56+0.44x48=48x(0.56+0.44)=48x1=48 或者=0.48x100x0.56+44x0.48=0.48x56+44x0.48=0.48x(56+44)=0.48x100=48

48+(0.48x25)=48+(0.12x4x25)=48+(0.12x100)=48+12=60答题不易,望采纳~~

63.9*0.48=(64-0.1)*(0.5-0.02)=32-1.28-0.05+0.002=30.672.
