To find the amount of sodium in 3 ounces of mixed nuts, you first need to determine the sodium content per ounce. If the nutritional information states that there are 2.25 mg of sodium in a certain amount (e.g., per serving), you'll typically need to find the sodium content per ounce by dividing the total sodium by the total ounces in that serving.
Here’s a step-by-step approach:
-
Determine the sodium content per ounce. If 2.25 (mg) is the sodium content in a specific amount (let's assume it's per 5 ounces as an example):
- Sodium per ounce = Total sodium / Total ounces.
- Sodium per ounce = 2.25 mg / 5 ounces = 0.45 mg per ounce.
-
Calculate the sodium in 3 ounces:
- Sodium in 3 ounces = Sodium per ounce × 3 ounces.
- Sodium in 3 ounces = 0.45 mg × 3 = 1.35 mg.
Now, based on your options, if we assume you need to calculate the sodium in 3 ounces by using the total sodium listed, the best method to find the amount of sodium in 3 ounces would be:
Multiply 3 times (Sodium per ounce), which is effectively calculating how much sodium is in 3 ounces based on its per-ounce content.
Given the choices you provided, "multiply 3 times 2.25" would give the sodium in 3 ounces if 2.25 is the content per ounce. (Assuming 2.25 mg is the sodium content for something like 5 ounces).
So, if 2.25 represents the sodium in a serum and you are calculating based on ounces, the correct option to pick would be multiply 3 times 2.25.
