Let's solve each of the fraction word problems step by step.

Problem 1:
Peter bought 8 hamburgers for his party. At the end of the party, 3 hamburgers were left. What fraction of the hamburgers were eaten?
- Total hamburgers = 8
- Hamburgers left = 3
- Hamburgers eaten = 8 - 3 = 5
So, the fraction eaten is:
$$
\frac{5}{8}
$$
✔ Answer: $\boxed{\frac{5}{8}}$ of the hamburgers were eaten.

Problem 2:
Cameron ate 3 slices of pizza. Samantha ate 2 slices of pizza. There are 8 slices in a pizza pie. What fraction of the pizza did Samantha eat? What fraction remains?
- Total slices = 8
- Samantha ate = 2 slices
- Fraction Samantha ate:
$$
\frac{2}{8} = \frac{1}{4}
$$
Now, total eaten = Cameron (3) + Samantha (2) = 5 slices
Slices remaining = 8 - 5 = 3
Fraction remaining:
$$
\frac{3}{8}
$$
✔ Answers:
- Samantha ate $\boxed{\frac{1}{4}}$ of the pizza.
- $\boxed{\frac{3}{8}}$ of the pizza remains.

Problem 4:
Mrs. Toomer brought 40 cookies to school. Mrs. Toomer’s class ate ½ of the cookies and Mrs. Smith’s class ate ¼ of the cookies. How many cookies are left?
- Total cookies = 40
- Mrs. Toomer’s class ate: $\frac{1}{2} \times 40 = 20$
- Mrs. Smith’s class ate: $\frac{1}{4} \times 40 = 10$
- Total eaten = 20 + 10 = 30
- Cookies left = 40 - 30 = 10
✔ Answer: $\boxed{10}$ cookies are left.

✔ Final Answers:
1. $\frac{5}{8}$
2. Samantha ate $\frac{1}{4}$; $\frac{3}{8}$ remains
3. $18
