We need to mix water and juice concentrate in the ratio of 7 : 2 to make orange juice. How much water do we need for 1 oz of the concentrate?
3.5
x/1 = 7/2
x = 7/2
To determine how much water is needed for 1 oz of the concentrate, we can set up a proportion based on the given ratio of water to juice concentrate.
The ratio of water to concentrate is 7:2, which means for every 7 parts of water, we need 2 parts of concentrate.
Let's assume the amount of water needed for 1 oz of concentrate is "x". The proportion can be set up as:
7/x = 2/1
To solve for "x", we can cross multiply:
7 * 1 = 2 * x
7 = 2x
Dividing both sides of the equation by 2:
7/2 = x
So, for 1 oz of concentrate, you would need 7/2 oz (or 3.5 oz) of water.
To determine how much water is needed for 1 oz of juice concentrate, we first need to find the total ratio of water to concentrate, which is 7:2.
The total ratio can be thought of as a total of 9 parts (7 parts water + 2 parts concentrate).
To find the amount of water needed for 1 oz of concentrate, we divide 1 oz by the total number of parts in the ratio (9).
(1 oz) / (7 + 2) = 1/9 oz
Therefore, you would need 1/9 oz of water for 1 oz of juice concentrate.
