Problem Analysis

The problem involves multi-step addition word problems where Donald and his father are competing to see who catches more prawns during a fishing trip. We need to calculate the total number of prawns caught by both in each hour and then find the overall totals.

Step-by-Step Solution

#### 1. First Hour
- Donald caught 17 prawns.
- His father caught 22 prawns.
- Total prawns caught in the first hour:
\[
17 + 22 = 39
\]

#### 2. Second Hour
- Donald caught 23 prawns.
- His father caught 12 prawns.
- Total prawns caught in the second hour:
\[
23 + 12 = 35
\]

#### 3. Third Hour
- Donald caught 24 prawns.
- His father caught 27 prawns.
- Total prawns caught in the third hour:
\[
24 + 27 = 51
\]

#### 4. Fourth Hour
- Donald caught 20 prawns.
- His father caught 20 prawns.
- Total prawns caught in the fourth hour:
\[
20 + 20 = 40
\]

#### 5. Total Prawns Caught in Four Hours
To find the total number of prawns caught by each person and the overall total, we will sum up their individual catches and the combined totals.

##### Donald's Total
- First hour: 17
- Second hour: 23
- Third hour: 24
- Fourth hour: 20
- Total prawns caught by Donald:
\[
17 + 23 + 24 + 20 = 84
\]

##### Father's Total
- First hour: 22
- Second hour: 12
- Third hour: 27
- Fourth hour: 20
- Total prawns caught by his father:
\[
22 + 12 + 27 + 20 = 81
\]

##### Overall Total
- Total prawns caught in all four hours (combined):
\[
39 + 35 + 51 + 40 = 165
\]
