Answer :

Certainly! Let's go step-by-step to answer the question.

1. Determine the percentage:

First, we need to find out what percentage 15 is out of 50. To do this, we use the formula:

[tex]\[ \text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100 \][/tex]

Here, the part is 15, and the whole is 50. Plugging these numbers into the formula, we get:

[tex]\[ \text{Percentage} = \left(\frac{15}{50}\right) \times 100 \][/tex]

Performing the division:

[tex]\[ \frac{15}{50} = 0.3 \][/tex]

Then, multiply by 100 to get the percentage:

[tex]\[ 0.3 \times 100 = 30 \][/tex]

So, 15 is 30% of 50.

2. Compare the percentage to given options:

The given options are:
- 30
- 35
- 25
- 40

The percentage we calculated is 30. Therefore, the option that matches this percentage is:

[tex]\[ \boxed{30} \][/tex]

3. Determine the largest fraction:

Next, we need to identify the largest fraction among the given options:
- [tex]\(\frac{30}{100}\)[/tex]
- [tex]\(\frac{35}{100}\)[/tex]
- [tex]\(\frac{25}{100}\)[/tex]
- [tex]\(\frac{40}{100}\)[/tex]

We can compare these fractions directly because they all have a common denominator (100). It means we just need to compare the numerators:
- 30
- 35
- 25
- 40

Clearly, 40 is the largest numerator. Therefore, the largest fraction is:

[tex]\[ \frac{40}{100} \][/tex]

So, summarizing:
- The percentage of 15 out of 50 is 30%.
- Among the options given, the number that represents this percentage is 30.
- The largest fraction given in the options is [tex]\(\frac{40}{100}\)[/tex].
