A measuring cup contains 1/5 of a cup of orange juice.It is then filled to the 1 cup mark with a mixture that contains equal amounts of orange,grapefruit,and pineapple juices.What fraction of the final mixture is orange juice?
The mixture is 1 - 1/5 = 4/5 of the cup,containing equal amounts of orange,grapefruit,and pineapple juices,so in this part,each juice is (4/5)*(1/3) = 4/15 of the cup; orange juice is 4/15 + 1/5 = 7/15 of the cup,therefore:
Orange juice:7/15
Grapefruit juice:4/15
pineapple juice:4/15
它的意思是有一个测量杯,里面已经有1/5杯的橙汁,然后又倒进另一个有刻度的杯子,里面已有等量的3样果汁【其中有一种是橙汁】。问:最后有多少量的橙汁在混合物中?【分数表示】
1/5+1/3*4/5=7/15
1-1/5=4/5
4/5÷3=4/15
4/15 + 1/5 =7/15
