Let’s go step by step to count the tally marks for each sport.

Remember:
Each group of 5 tally marks looks like this: four vertical lines with a diagonal line crossing them (like “||||” with a slash through). That equals 5.
Any extra lines after that are just single counts.

1. Football:

Tally marks shown: Two full groups of 5, plus one extra line.

So:
5 + 5 + 1 = 11

→ 11 people like football.

---

2. Basketball:

Tally marks shown: Three full groups of 5, plus three extra lines.

So:
5 + 5 + 5 + 3 = 18

→ 18 people like basketball.

---

3. Soccer:

Tally marks shown: Two full groups of 5, plus two extra lines.

So:
5 + 5 + 2 = 12

→ 12 people like soccer.

Now let’s answer the rest:

4. Which had the most?

Compare:
Football = 11
Basketball = 18
Soccer = 12

Biggest number is 18 → basketball

---

5. Which had the least?

Smallest number is 11 → football

---

6. How many more like basketball than soccer?

Basketball: 18
Soccer: 12

Subtract: 18 - 12 = 6

→ 6 more people like basketball than soccer.

Final Answer:
1. 11
