Answer 1

To create a ratio table based on the given ratio of 5 females for every 3 males, we can set it up as follows:

1. Start with the known ratio:
- Males: 3
- Females: 5

2. From this ratio, we can find out how many females correspond to 15 males.

3. We can find the scale factor by comparing the new number of males to the original number of males in the ratio:
\[
\text{Scale Factor} = \frac{15 \text{ males}}{3 \text{ males}} = 5
\]

4. Now, we multiply the corresponding number of females by the same scale factor:
\[
\text{Number of Females} = 5 \text{ females} \times 5 = 25
\]

Now we can fill in the ratio table:

| Males | Females |
|-------|---------|
| 3 | 5 |
| 6 | 10 |
| 9 | 15 |
| 12 | 20 |
| 15 | 25 |

So, if there are 15 males in the class, there would be **25 females**.
