Thus -- of every 12 ounces -- 2 ounces are grape juice, 3 ounces are orange juice, and 7 ounces are pineapple juice. Since grape juice constitutes 2 of every 12 ounces, the amount of grape juice is equal to 2/12 of the total: (2/12)(156) = 2*13 = 26.

We're asked for the number of ounces of grape juice in the punch. This question can be approached in a number of different ways, including by just listing out the multiples until you get to the correct answer. Based on the given ratio, we could have... 2 ounces grape juice + 3 ounces orange juice + 7 ounces pineapple juice --> 12 total ounces of punch re: 2 + 3 + 7 = 12 Increasing each 'part' accordingly, we could have: 4 + 6 + 14 = 24 ounces of punch 6 + 9 + 21 = 36 ounces of punch 8 + 12 + 28 = 48 ounces of punch Etc. At this point, you should notice that we're increasing the total in 'sets' of 12 ounces, so we can divide 156 by 12.... 156/12 = 13 sets of 12 ounces. Each of those sets contains 2 ounces of grape juice, so we have (13)(2) = 26 ounces of grape juice in total.

A. 13 B. 26 C. 39 D. 91 E. 130 OA B Since the ingredients are mixed in a ratio of 2:3:7, there are 2x ounces of grape juice, 3x ounces of orange juice, and 7x ounces of pineapple juice in this punch for some number x. We can create the equation: 2x + 3x + 7x = 156 12x = 156 x = 13 So there are 2(13) = 26 ounces of grape juice in the punch.
