6.75-2.75/{10%*(9.75-4又1/4)}怎么简便啊!
6.75-2.75/{10%*(9.75-4又1/4)}
怎么简便啊!
6.75-2.75/{10%*(9.75-4又1/4)}怎么简便啊!
6.75-2.75/{10%*(9.75-4又1/4)}
=6.75-275/100/[10/100*(975/100-425/100)]
=6.75-275/100/[10/100*(550/100)]
=6.75-275/100/(55/100)
=6.75-275/55
=6.75-5
=1.75
6.75-2.75/{10%*(9.75-4又1/4)}
=6.75-275/100/[10/100*(975/100-425/100)]
=6.75-275/100/[10/100*(550/100)]
=6.75-275/100/(55/100)
=6.75-275/55
=6.75-5
=1.75
6.75-2.75除以{10%乘（9.75减四分之十七）}
6.75－2.75÷[10%×（9.75－4又4/1）]能简算就简算
6.75-2.75/{10%*(9.75-4又1/4)}怎么简便啊!
6.75—2.75/[10%x(9.75—4+1/4)]简便的
6.75-2.75 除以[10%乘（9.75-4又4分之1）]
6.76-2.75/[10%*(9.75-4.25)]请高手脱式计算
希望能把过程写下,这样我看得明白.（1）[（0.6—1/4）×4/7+3/10 ]÷50%=（2）6.75—2.75÷[10%×（9.75—4又1/4）]=（3）3.6÷2.4+5.5×4/5—6又1/2×0.6=（4）8/15÷[5/32×（9/10+1/6）]=
6.75乘以0.25-2.75除以4的简便运算
6.75减去某数的5倍得2.75,求某数
6.75减去一个数的5倍得2.75,求这个 数的多少
2.75*10+7.25*10简便计算
5+(80-5X+10)×5%=6.75
简算：6.75+6.75*7.6+1.4*6.75
9.75÷0.15竖式
6.7＋5x＝9.75 10x＋8.5×3＝30.5 完整的写出来,
39.9*2.75+27.5*611-2.75
2.75除以2.5减10分之7乘2分之1用简便方法计算
解方程.6分之5+X=10分之9 4分之3X+6.75X=7.5
