o.25x4.8x0.5的简便计算

o.25x4.8x0.5 =0.25×4×1.2×0.5 =0.25×4×0.6×2×0.5 =1×0.6×1 =0.6

0.25*4.8*0.5 =0.25X4X0.6X0.5 =1X0.3 =0.3

4.8-4.8X0.5 =4.8x(1-0.5) =4.8x0.5 =2.4 祝天天向上。

4.8-4.8*0.5=4.8*(1-0.5)=4.8*0.5=2.4

4.8-4.8x0.5 =4.8-2.4 =2.4

原式 = 4.8×(1-0.5) = 4.8×0.5 = 4.8÷2 = 2.4

原式 =0.85x0.5+0.25x2x0.15 =0.85x0.5+0.5x0.15 =(0.85+0.15)x0.5 =1x0.5 =0.5

=0.125x8x0.25x4x0.5x2 =1x1x1 =1

(1)4.8×2.12 解:原式=(4×2)+(0.8×0.12) =8+0.096 =8.096 (2)6 .27×5.2 解:原式=(6×5)+(0.27×0.2) =30+0.054 =30.054 (3)4.15×0.8 解:原式=4+(0.15×0.8) =4+0.12 =4.12
