To find the amount of sodium in 3 ounces of mixed nuts, you need to know the sodium content per ounce first. If the chart specifies that there are 2.25 milligrams of sodium in a certain amount of mixed nuts, you'll need to determine how many ounces correspond to that amount.
If the 2.25 mg of sodium is for a larger amount (like 5 cups), you can calculate the sodium content per ounce and then multiply that by 3 ounces:
- Divide the total sodium amount (2.25 mg) by the total number of ounces in 5 cups (which you need to convert to ounces, knowing that 1 cup is 8 ounces, so 5 cups = 40 ounces) to get the sodium per ounce.
- Then, multiply that result by 3 to find the sodium in 3 ounces.
Therefore, the best method from your options is:
multiply 3 times 2.25 (this assumes you correctly found the sodium content per ounce first, which would generally not result in exactly 2.25 directly).
However, the correct approach in context would typically require first figuring out the sodium per ounce, which isn't presented directly in your choices. But in line with the options given—if you interpret it as simply taking 3 ounces of mixed nuts at 2.25 mg for a total amount, then choosing multiply 3 times 2.25 could be acceptable in a simplified context without additional calculation given.
