Question

A recipe that makes 7 servings calls for 1/2 cup of apple juice and 2/3 cup of cranberry juice.

How many cups of juice are there per serving?

A. 1/6


B. 3/5


C. 1 1/16


D. 8 1/6

Answer 1

apple juice + cranberry juice = total juice
1/2 + 2/3 = total juice
3/6 + 4/6 = total juice
7/6 = total juice

so 7 servings calls for 7/6 cups of juice.....
7/(7/6) = 1/x --- (7 serv to 7/6 cup of j = 1 serv to x cups of j)
cross multiply
(7)(x) = (7/6)(1)
7x = 7/6
x = (7/6) / 7
x = 7/6 * 1/7
x = 7/42 which reduces to 1/6

so 1 servings calls for 1/6 cups of juice

any questions ?
