把果粉和水按1:250的比例配制成果汁.100g的水,能配制成这种果汁多少g?

30x10=300
2.2x1÷(1+10)=0.2
一种果汁,果粉和水的比是1:10,30克果粉应加入(30)克的水,如果要配制2.2千克的果汁,需要加入果粉（0.2）千克

【Is the theme of the design scheme for a" blink,fruit sugar,Germany ".Because in a variety of fruit flavors of candy as the main body,so a separate with cartoon characters of strawberry anthropomorphic design.With the brief strokes of humor,let the more interesting posters and communication.The feeling of bright orange red) has been used in color as fundamental key,more sweet and lively sense.Design scheme is the theme of the second "maverick,enough flash just right",so in order to fit the theme,using the reverse design.Large font design for motion picture attached.Dark and strong contrast color,also make the poster more powerful.】

方程 解 设需果粉x千克 则
x＋11x＝726 解得x＝66 66×10＝660（千克）
算数 726÷（1＋11）＝66（千克） 66×10＝660（千克）
答：需果粉66千克 水660千克

以前十两为一斤的计量法中的半两就是25克.分析天平和架盘天平都能称出25克.砝码用两个10克加一个5克.秤的感量比25克大就称不出25克,因为灵敏度
不够.

3+47=50
6÷（3／50）=100（千克）
答：那么6kg果粉能配制100千克果汁.
