39*148/149+148*86/149+48*74/149
39*148/149+148*86/149+48*74/149
解方程:39*149分之148+148*149分之86+48*149分之74
(1)39*149分之148+148*149分之86+48*149分之74
39乘以148/149+148乘以86/149+48乘以74/149
39*(148/149)+148*(74/149)=?
39*148\149+148*74\149
39乘149分之148加148乘149分之86加48乘149分之74 等于多少
39乘149分之148加148乘149分之86加48乘149分之74
39乘149分之148加上148乘以149分之86加48乘以149分之74用简便算法计算
39乘以149分之148乘以149分之86加48乘以149分之74等于? 俺要简便方法,就在今天
39×148/169+148×86/149+48×74/169 41又1/3×3/4+51又1/4×4/5+61又1/5
3 (148~149)
