Problem 5:

> How many prawns did they catch each in four hours and how many prawns did they catch altogether?

This is a multi-step problem. We need to:
1. Find how many prawns Donald caught in total over 4 hours.
2. Find how many prawns his father caught in total over 4 hours.
3. Add both totals to get the combined total.

#### Step 1: Donald’s total catch

- 1st hour: 17
- 2nd hour: 23
- 3rd hour: 24
- 4th hour: 20

Add them up:

$$
17 + 23 = 40 \\
40 + 24 = 64 \\
64 + 20 = 84
$$

So, Donald caught 84 prawns in total.

---

#### Step 2: Father’s total catch

- 1st hour: 22
- 2nd hour: 12
- 3rd hour: 27
- 4th hour: 20

Add them up:

$$
22 + 12 = 34 \\
34 + 27 = 61 \\
61 + 20 = 81
$$

So, the father caught 81 prawns in total.

---

#### Step 3: Total prawns caught together

Now add both totals:

$$
84 + 81 = 165
$$

✔ Answer:
- Donald caught 84 prawns.
- His father caught 81 prawns.
- Together, they caught 165 prawns in four hours.

🔍 Explanation:

These are addition word problems, some requiring simple addition (Q1–Q4), while Q5 requires multiple steps:
- Summing individual totals over time,
- Then combining those totals.

This helps build skills in:
- Reading comprehension,
- Organizing data,
- Performing multi-step calculations.
