设苹果88-x个,则梨有x个所以依题意1/3x*0.5+1/4(88-x)*0.7=15所以x= .剩下的会了吧
5年级的题?我外甥现在在学这个。
设梨有X个 苹果有Y个 那么X+Y=88 3/X*0.5+4/Y*0.7=15元 那个*是乘以的意思 算出苹果和梨格多少个 然后你知道了吧
设苹果数量为x,梨数量为y,则有0.7*1/4x+0.5*1/3y=15x+y=88解这个方程组可得:x=40,y=48所以全买下需要:0.5*y+0.7*x=52元
设有X个梨,y个苹果0.5x
0.7x---- + ------=153
4解出X,y再分别乘以价钱就行了解说:1/3的梨的个数乘以梨的单价,加1/4个苹果的个数乘以单价等于15元 还有x+y=88和上面的解出来的式子组成方程组,就行了。
设梨有X个,则苹果有(88-X)个,根据题意有
0.5×(1/3)X + 0.7×【1/4×(88-X)】= 15
所以,梨有48个,苹果有40个
所以有:0.5×48+0.7×40=52(元)这个答案可满意?
设梨X个,苹果Y个。得出方程x+y=88 1/3*0.5X+1/4*0.7Y=15 解得X=48 Y=400.488乘0.25保留一位小数,约等于多少?_百度作业帮

0.488乘0.25保留一位小数,约等于多少?
