列竖式计算2.5(0.70.4)

列竖式计算2.5(0.70.4) =5/2×0.28 =5×0.14 =0.7

应该用简便计算 =2.5χ0.4χ0.7 =1χ0.7 =0.7

试题答案:5×1.8=9.0.1.8×5.9.056÷0.7=80.807560560

列竖式计算 (4+0.4)2.5 =4×2.5+0.4×2.5 =10+1 =11

列竖式计算 2.5Ⅹ(0.7Ⅹ0.4) =2.5x0.4x0.7 =1x0.7 =0.7

0.05×520×0.4×2.4 =26×0.4×2.4 =10.4×2.4 =24.96 竖式见图

(1)73.1×2.5=182.75; . 36 5 5 146

“ 1.8x23 ”的竖式计算如图: “0.37x0.4” 的竖式计算入图: “1.06x25”

列竖式计算 1.25X0.4X80X2.5 =(1.25x80)x(0.4x2.5) =100
