Let’s solve each question step by step.

---

Question 1:
Donald caught 17, his father caught 22.
Add them:
17 + 22 = 39

→ They caught 39 prawns in the first hour altogether.

---

Question 2:
Donald caught 23, his father caught 12.
Add them:
23 + 12 = 35

→ They caught 35 prawns in the second hour altogether.

---

Question 3:
Donald caught 24, his father caught 27.
Add them:
24 + 27 = 51

→ They caught 51 prawns in the third hour altogether.

---

Question 4:
Donald caught 20, his father caught 20.
Add them:
20 + 20 = 40

→ They caught 40 prawns in the fourth hour altogether.

---

Question 5:
We need to find:
- How many prawns Donald caught in total over 4 hours.
- How many prawns his father caught in total over 4 hours.
- And how many they caught together in total.

First, let’s add up Donald’s catches:

Hour 1: 17
Hour 2: 23
Hour 3: 24
Hour 4: 20

Donald’s total = 17 + 23 + 24 + 20

Step-by-step:
17 + 23 = 40
40 + 24 = 64
64 + 20 = 84

→ Donald caught 84 prawns in 4 hours.

Now, his father’s catches:

Hour 1: 22
Hour 2: 12
Hour 3: 27
Hour 4: 20

Father’s total = 22 + 12 + 27 + 20

Step-by-step:
22 + 12 = 34
34 + 27 = 61
61 + 20 = 81

→ His father caught 81 prawns in 4 hours.

Total together = Donald’s total + Father’s total = 84 + 81 = 165

Alternatively, we can also add the hourly totals from Questions 1–4:

Q1: 39
Q2: 35
Q3: 51
Q4: 40

Total = 39 + 35 + 51 + 40

39 + 35 = 74
74 + 51 = 125
125 + 40 = 165 → Same answer! Good check.

Final Answer:
1. 39
2. 35
3. 51
4. 40
5. Donald: 84, Father: 81, Together: 165
