Question

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

how much cranberry juice ?

Answer 2

oh sorry 2/3

Answer 3

add the juices
1/2 + 2/3 = 3/6 + 4/6 = 7/6

so there is 7/6 cups of juice for 7 servings. To find out how many are for each serving, we will use a proportion.

(7/6) / 7 = x/1 --- (7/6 cups of j to 7 serv = x cups of j to 1 serv
cross multiply
7x = 7/6 -- divide by 7
x = (7/6) / 7
x = 7/6 * 1/7
x = 7/42 which reduces to 1/6 cups per serving

check..
1/6 * 7 = 7/6
7/6 = 7/6 (correct)

answer is 1/6 cups of juice per serving

A recipe that makes 6 servings calls for 1/3 cup of orange juice and 1/2 cup of lemonade. Arlene modifies the recipe so that it can serve 9.



How many cups of orange juice does Arlene need?

Answer 9

6/(1/3) = 9/x -- (6 serv to 1/3 o.j. = 9 serv to x cups o.j.)
cross multiply
6x = (1/3)(9)
6x = 3
x = 3/6 which reduces to 1/2 cups of o.j. for 9 servings

answer is 1/2 cups of orange juice for 9 servings

Answer 10

A recipe for potting soil that makes enough to fill 3 bags calls for 5 1/2 lb of compost. David wants to modify the recipe so that it fills 5 bags.



How many more pounds of compost will David need for the modified recipe than the original recipe calls for?

Answer 11

5 1/2 = 11/2

3/(11/2) = 5/x -- (3 bags to 11/2 lbs = 5 bags to x lbs)
cross multiply
3x = (11/2)(5)
3x = 55/2
x = (55/2) / 3
x = 55/2 * 1/3
x = 55/6 which equals 9 1/6 lbs

so he needs 9 1/6 (or 55/6) lbs and he has 5 1/2 (or 11/2) lbs
55/6 - 11/2 = 55/6 - 33/6 = 22/6 which equals 3 2/3 lbs

he needs 3 2/3 more lbs
