according ot he directions on a can of frozen orange juice concentrate, 1 can of concentrate is to be mixed with 3cans of water to make orange juice. How many 12-ounce cans of the concentrate are required to prepare 2006-ounce servings of arange juice
a25 b34 c50 d67 d100
看上去蛮幼稚一题, 但题意我不能正确理解, 求做法谢谢

这题题目抄错了,应该是问多少个12-ounce cans可以准备200个6-ounce的橙汁,而不是准备2006-ounce的橙汁。
1 can of concentrate需要混合3 cans水即可获得混合好的橙汁,即一份混合好的橙汁中有1/4的concentrate。200个6-ounce橙汁即1200-ounce橙汁需要concentrate:1200/4=300-ounce,300-ounce concentrate需要12-ounce:300/12=25 cans。
