If a portion of tuna salad is 5 ounces in a total sandwich of 15 ounces, what percentage is the tuna salad?

If a portion of tuna salad is 5 ounces in a total sandwich of 15 ounces, what percentage is the tuna salad?

• A. 25%
• B. 33.33%
• C. 50%
• D. 20%

Answer: (B)

To find the percentage of tuna salad in the sandwich, you need to calculate the proportion of the tuna salad's weight relative to the total weight of the sandwich. The formula for calculating the percentage is: \[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 \] In this case, the "part" is the weight of the tuna salad, which is 5 ounces, and the "whole" is the total weight of the sandwich, which is 15 ounces. Substituting the values into the formula gives: \[ \text{Percentage} = \left( \frac{5}{15} \right) \times 100 \] Simplifying the fraction \( \frac{5}{15} \) results in \( \frac{1}{3} \), and then we multiply by 100 to convert it into a percentage: \[ \text{Percentage} = \left( \frac{1}{3} \right) \times 100 \approx 33.33 \] Thus, the percentage of the tuna salad in the sandwich is approximately 33.33%. This is the correct choice

To find the percentage of tuna salad in the sandwich, you need to calculate the proportion of the tuna salad's weight relative to the total weight of the sandwich. The formula for calculating the percentage is:

[

\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100

]

In this case, the "part" is the weight of the tuna salad, which is 5 ounces, and the "whole" is the total weight of the sandwich, which is 15 ounces.

Substituting the values into the formula gives:

[

\text{Percentage} = \left( \frac{5}{15} \right) \times 100

]

Simplifying the fraction ( \frac{5}{15} ) results in ( \frac{1}{3} ), and then we multiply by 100 to convert it into a percentage:

[

\text{Percentage} = \left( \frac{1}{3} \right) \times 100 \approx 33.33

]

Thus, the percentage of the tuna salad in the sandwich is approximately 33.33%. This is the correct choice
