0.8×(12.5+1.25)的简便计算

0.8×125+12.5+1.25 =100+13.75 =113.75 直接算最简单

0.8✘1.25+0.8✘12.5

简便计算 0.8x(12.5+1.25) =0.8x12.5+0.8x1.25 =10+1 =11

12.5*8+1.25*8+0.125*8

(1.25+12.5+0.125)×8 =1.25×8+12.5×8+0.125×8 =10+100+1 =111。满意请采纳。

1.25*1.12*(40.5+39.5)=1.25*80*1.12=112

32x1.25X12.5 =4x8x1.25x12.5 =(4x12.5)x(8x1.25) =50x10 =500 望采纳! 有不会的可以随时来问我哦~

(1.25×3.75×3.9)÷(0.39×12.5×37.5) =1.25×3.75×3.9÷0.39÷12.5÷37.5 =(1.25÷12.5)×(3.75÷37.5)×(3.9÷0.39) =0.1×0.1×10 =0.1

1.25*460+125*45-12.5=6187.5 6187.5+12.5=1.25*460+125*45 6187.5+12.5-125*45=1.25*460 当然,先把乘的结果算出来再验

(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.
