Final answer:
There is approximately 0.4583 teaspoons of sugar in one ounce of a 12-ounce soda.
Step-by-step explanation:
In order to find out how much sugar is in one ounce of a 12-ounce soda, we can set up a proportion. We know that a 12-ounce soda contains 5 1/2 teaspoons of sugar. Let x represent the amount of sugar in one ounce. The proportion can be set up as 5.5 teaspoons / 12 ounces = x teaspoons / 1 ounce.
To solve for x, we can cross-multiply. 12 * x = 5.5 * 1. This simplifies to 12x = 5.5.
Dividing both sides by 12, we get x = 5.5 / 12 = 0.4583 teaspoons. Therefore, there is approximately 0.4583 teaspoons of sugar in one ounce of the soda.
