2.4x3 0.8的脱式计算

2.4x3÷0.18=7.2÷0.18=40

24x3÷018=72÷018=40

你好!2.4x0.8÷0.24=2.4÷0.24*0.8=10*0.8=8 仅代表个人观点,不喜勿喷,谢谢.

1、直接写出得数.0.45*2.5=1.1250.8*1.25=10.3*3.6=1.080.3*0.3=0.0910*0.07=0.70.92*0.4=0.3680.2*0.26=0.0520.14*4=0.560.02*0.1=0.0021.2*0.3=0.362.5*0.4=12.4*5=120.22*4=0.883.25*0=00.9-0.52=0.383.99*1=3.990*3.52=012.5*8=

原式=2.7x100+2.7x2 =270+5.4 =275.4

脱式计算2.4x4.5=2.4x0.5x9=1.2x9=10.8

=2.4*(10-0.1)=2.4*10-2.4*0.1=24-0.24=23.76

2.4 x 2.5 + 1.6 x 2.5= 2.5 x (2.4 + 1.6)= 2.5 x 4.0= 10.02.4 x 2.5 - 1.6 x 2.5= 2.5 x (2.4 - 1.6)= 2.5 x 0.8= 2.0

2.4x0.7÷2.4*0.7脱式计算2.4x0.7÷2.4*0.7=2.4÷2.4*0.7x0.7=1x0.49=0.49希望能帮到你

0.86x2.4+2.4x0.14=2.4x(0.86+0.14)=2.4x1=2.4
