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

12.5×8÷12.5×8 =(12.5÷12.5)x(8x8) =1x64 =64

解: 80÷12.5 =80÷25×2 =160÷25 =6.4 答案是: 6.4

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

3.25除以12.5除以0.8的脱式计算 3.25除以12.5除以0.8 =3.25÷(12.5*0.8) =3.25÷10 =0.325

(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.

(1)(12.5+7.5)÷0.25 =20÷0.25=80(2)2÷85×254=2×58×254=71316(3)13.1×56+5.6×69=131×5.6+5.6×69=5.6×(131+69)=5.6×200=1120(4)2.8+[2.4÷(90-60)]=2.8+[2.4÷30]=2.8+0.08=2.88

7.42除以十二点五除以八脱式计算怎么算 7.42÷12.5÷8 =7.42÷(12.5×8) =7.42÷100 =0.0742

应该是 8.8×12.5 =11×0.8×12.5 =11×(0.8×12.5) =11×10 =110

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