The image contains a math problem in Catalan related to forming two-digit numbers using the digits 2, 6, and 7. Here's a breakdown of the task:

### Problem Description (Translated from Catalan):

**Title: Form Numbers**  
_Numbers with Two Digits_  
We want to know all the two-digit numbers that can be formed using the digits 2, 6, and 7.

---

### Questions:

**a)** _How many two-digit numbers can be formed?_

_Answer:_ You can form **__** two-digit numbers.

**b)** _How many different two-digit numbers can be formed?_

_Answer:_ You can form **__** different two-digit numbers.

---

### Solution:

1. **For part (a):**  
Each two-digit number can be formed by choosing a digit for the tens place and another digit for the ones place.  
Since we have the digits 2, 6, and 7 available, there are 3 choices for the tens place and 3 choices for the ones place.  
Thus, the total number of possible two-digit numbers (including repetitions) is:

\[
3 \times 3 = 9
\]

So, there are **9** possible two-digit numbers.

---

2. **For part (b):**  
Here, we are asked to form two-digit numbers where the two digits are different.  
For the tens place, we still have 3 choices, but once we pick a digit for the tens place, we have only 2 remaining choices for the ones place (since the digits must be different).  
Therefore, the total number of two-digit numbers with different digits is:

\[
3 \times 2 = 6
\]

So, there are **6** different two-digit numbers.

---

### Final Answers:
- **(a)** There are **9** two-digit numbers in total.
- **(b)** There are **6** different two-digit numbers.
