Question

A recipe for sparkling grape juice calls for

Answer 1

A) 3/4 is equal to 0.75. 1/2 is equal to 0.5. You need to find out how many parts of the grape juice you have. So you take your 9 quarts and divide it by 0.75. That equals 12. So for the 9 quarts you need, you will add 12 parts of the 3/4. Now you need to add 12 1/2s as well. So 1/2 (or 0.5) multiplied by 12 is 6. So your answer would be 6 quarts

Answer 2

Answer:. A.) 6 quarts

B.) 45/8 quarts

C. 40 quarts sparkling water and 60 quarts of grape juice.

Once you get the basic ratio which is the amount of sparkling water is 2/3 the amount of grape juice, you can use that to set up as n equation for the next two questions.

Step-by-step explanation:

15/4 = 2x/3

Multiply both sides by the reciprocal:

3/2(15/4 = 3/2(2x/3)

45/8 = x

That is 5 5/8 quarts when simplified.

15/4 is 3 3/4 quarts

2 parts sparkling water to 3 parts grape juice is another useful ratio. Using that, 2x + 3x= 100 we can calculate

5x = 100

x 20. 2(20)=40 and 3(20)= 60
