Let’s go through each question one by one, using the two pie charts provided:

🐠 Favorite Pet Pie Chart Data:
- Fish: 28%
- Snake: ? (We’ll calculate)
- Dog: 15%
- Gerbil: 15%
- Spider: 11%
- Cat: 9%
First, let’s find the percentage for
Snake, since all percentages in a pie chart must add to 100%.
> 28% (fish) + 15% (dog) + 15% (gerbil) + 11% (spider) + 9% (cat) =
78%
So,
Snake = 100% - 78% = 22%
✔ Now we have:
- Fish: 28%
- Snake: 22%
- Dog: 15%
- Gerbil: 15%
- Spider: 11%
- Cat: 9%
