125÷(12.5 ÷0.08 )脱式计算点算法

125÷(12.5 ÷0.08 ) =125÷12.5/0.08 =125x0.08/12.5 =10x0.08 =0.8 谢谢,请采纳

用简算,这样最方便 12÷12.5 =(12×8)÷(12.5×8) =96÷100 =0.96

(1)0.8×(12.5+1.25)=0.8×12.5+0.8×1.25=10+1=11;(2)7.75×[20÷(3.24-3.04)=7.75×(20÷0.2)=7.75×100=775;(3)4.05÷0.81+2.4=5+2.4=7.4.

12.8×0.5x4.8÷1.5 =6.4x4.8÷1.5 =30.72÷1.5 =20.48

35.8÷12.5÷0.8-0.15 =35.8÷(12.5×0.8)-0.15 =35.8÷10-0.15 =3.58-0.15 =3.43

0.125÷12.5%x(2/3+0.5) =0.125x100/12.5x(2/3+0.5) =1x(2/3+0.5) =2/3+1/2 =4/6+3/6 =7/6

1.46×5+12.8÷0.4×7.5 =1.46×5+3.2×7.5 =1.46x5+3.2x1.5x5 =1.46x5+4.8x5 =(1.46+4.8)x5 =6.26x5 =31.3 希望帮到你 望采纳 谢谢 加油

原式 =(12.5x0.8)x(0.5x0.4) =10x0.2 =2

4.8÷1/5+12×20%脱式计算 =4.8x5+12x0.2 =24+2.4 =26.4
