0.425*0.38/0.01怎么简算

0.425*0.38/0.01 怎么简算 = 4.25*3.8 = (17/4)*(4-0.2) = 17 - 3.4/4 = 17 - 1.7/2 = 17-0.85 = 16.15

4.25X0.16+264X0.0425+5.2X4.25+0.425X20 =4.25x0.16+2.64x4.25+5.2x4.25+4.25x2 =4.25x(0.16+2.64+5.2+2) =4.25x10 =42.5

12.5×0.0275+1.25×0.425+12.5% =12.5*(0.0275+0.0425+0.01) =12.5*0.08 =12.5*8/100 =1

4.25×18+0.425x820 =4.25×18+4.25×82 =4.25×(18+82) =4.25×100 =425

解: 4.25×10.1-0.425=4.25*(10.1-0.1)=4.25*10=42.5

121159乘0.425=51492.575 希望能帮到你,祝你学习愉快

425X0.043+42.5X1.42+0.425X15 =42.5X(0.43+1.42+0.15) =42.5X2 =85

=7.89x(0.575+0.425) =7.89x1 =7.89

解0.425 —-0.008 —————— --.-3400 0.425*0.008=0.0034 小数乘以小数被乘数一共有六位小数就从乘积末尾数出六位点上小数点,并划去小数末尾的二个0,结果为0.0034

0.425变成分数; 最简分数结果是40分之17; 0.425 =425/1000 =85/200 =17/40
