An 8-ounce glass of orange juice contains 72 milligrams of vitamin C. How much juice contains 36 milligrams of vitamin C?
Isn't 36 half of 72?
What is half of 8?
To find out how much juice contains 36 milligrams of vitamin C, we can set up a proportion based on the information given.
We know that an 8-ounce glass of orange juice contains 72 milligrams of vitamin C. Let's call the unknown amount of juice "x".
The proportion can be set up as follows:
8 ounces of juice / 72 milligrams of vitamin C = x ounces of juice / 36 milligrams of vitamin C
Now, we can solve for x by cross-multiplying:
8 * 36 = 72 * x
288 = 72x
Divide both sides of the equation by 72 to isolate x:
288 / 72 = x
4 = x
Therefore, 4 ounces of juice contains 36 milligrams of vitamin C.
