Let’s solve each problem one by one, step by step. We’ll use multiplication and division as needed.

Problem 1:
Each pizza oven costs $2,700. There are 6 ovens.
To find total cost: multiply cost per oven by number of ovens.
→ 2,700 × 6 = ?
Break it down:
2,000 × 6 = 12,000
700 × 6 = 4,200
Add them: 12,000 + 4,200 =
16,200
✔ Final Answer for #1:
$16,200

Problem 2:
Each oven produces 304 slices. Each pizza has 8 slices.
First, find how many pizzas ONE oven makes:
→ 304 ÷ 8 = ?
304 ÷ 8:
8 × 38 = 304 → so 38 pizzas per oven.
Now, there are 6 ovens:
→ 38 × 6 = ?
30 × 6 = 180
8 × 6 = 48
180 + 48 =
228
✔ Final Answer for #2:
228 pizzas
---
Problem 3:
Each oven bakes 1 pizza in 12 minutes. How many pizzas can all 6 ovens bake in 3 hours?
First, convert 3 hours to minutes:
→ 3 × 60 = 180 minutes
How many 12-minute intervals in 180 minutes?
→ 180 ÷ 12 = 15
So each oven can bake 15 pizzas in 3 hours.
Now, 6 ovens:
→ 15 × 6 =
90
✔ Final Answer for #3:
90 pizzas
---
Problem 4:
Order is for 240 pizzas. One oven is broken → only 5 working ovens.
They must share the work equally.
Divide total pizzas by number of working ovens:
→ 240 ÷ 5 = ?
5 × 48 = 240 → so
48
✔ Final Answer for #4:
48 pizzas per oven
---
Problem 5:
Total cleaning time = 162 minutes. Each staff member works 18 minutes.
How many staff members?
Divide total time by time per person:
→ 162 ÷ 18 = ?
18 × 9 = 162 → so
9
✔ Final Answer for #5:
9 staff members
---
Problem 6:
On Friday night, each oven produces 48 pizzas. 6 ovens → total pizzas?
→ 48 × 6 = 288 pizzas
Each pizza has 8 slices → total slices?
→ 288 × 8 = ?
200 × 8 = 1,600
80 × 8 = 640
8 × 8 = 64
Add: 1,600 + 640 = 2,240; 2,240 + 64 =
2,304 slices
Served to 768 guests. Each guest eats same number of slices.
→ 2,304 ÷ 768 = ?
Let’s divide:
768 × 3 = 2,304 → exactly!
✔ Final Answer for #6:
3 slices per guest
---
Final Answer:
1) $16,200
2) 228 pizzas
3) 90 pizzas
4) 48 pizzas
5) 9 staff members
6) 3 slices
