Let’s solve each problem one by one, step by step.

Problem 1:
The chicken pen held 7 chickens.
Each chicken lays 6 eggs a day.
We want to know how many eggs they get altogether after 30 days.
Step 1: Find how many eggs all 7 chickens lay in
one day.
→ 7 chickens × 6 eggs =
42 eggs per day
Step 2: Multiply that by 30 days.
→ 42 eggs/day × 30 days = ?
Let’s calculate:
42 × 30 = (40 × 30) + (2 × 30) = 1200 + 60 =
1260
✔ So, total eggs after 30 days =
1260

Problem 2:
Simone cut 4 pieces of wood:
4.2m, 3.5m, 3.7m, and 9.2m.
She put them together to make one long piece. How long is it?
We just add all the lengths:
Start with 4.2 + 3.5 =
7.7
Then 7.7 + 3.7 =
11.4
Then 11.4 + 9.2 =
20.6
✔ Total length =
20.6 meters

Problem 3:
Patrick ordered 9 pizzas.
Each pizza has 8 slices.
There are 12 people at the party (including Patrick).
How many slices does each person get?
Step 1: Total slices = 9 pizzas × 8 slices =
72 slices
Step 2: Divide equally among 12 people → 72 ÷ 12 =
6
✔ Each person gets
6 slices

Problem 4:
A car company made 12 cars per week for 4 weeks.
Then they doubled that amount over the next 4 weeks.
How many cars did they make after 8 weeks?
First 4 weeks:
12 cars/week × 4 weeks =
48 cars
Next 4 weeks: They doubled the weekly amount → 12 × 2 =
24 cars per week
So, 24 cars/week × 4 weeks =
96 cars
Total after 8 weeks: 48 + 96 =
144 cars
✔ Final answer =
144 cars

Final Answer:
1. 1260
2. 20.6
3. 6
4. 144
