Let's solve each of the multiplication word problems step by step.

Problem 1:
A supermarket placed an order of 2485 sets of kitchen utensils every month. Calculate the total orders for 8 months.
####
Step-by-step Solution:
We are given:
- Monthly order = 2,485 sets
- Number of months = 8
To find the total number of sets ordered in 8 months, multiply the monthly order by the number of months:
$$
2485 \times 8
$$
Now calculate:
$$
2485 \times 8 = (2000 + 400 + 80 + 5) \times 8
$$
Break it down:
- $2000 \times 8 = 16,000$
- $400 \times 8 = 3,200$
- $80 \times 8 = 640$
- $5 \times 8 = 40$
Now add them up:
$$
16,000 + 3,200 = 19,200 \\
19,200 + 640 = 19,840 \\
19,840 + 40 = 19,880
$$
✔ Answer: The total orders for 8 months =
19,880 sets

Problem 2:
Every month a grocery orders the same number of eggs, which is 8280 from a dairy farm. What is the total number of eggs ordered in 6 months?
####
Step-by-step Solution:
We are given:
- Monthly egg order = 8,280
- Number of months = 6
Total eggs in 6 months = $8280 \times 6$
Calculate:
$$
8280 \times 6 = (8000 + 200 + 80) \times 6
$$
Break it down:
- $8000 \times 6 = 48,000$
- $200 \times 6 = 1,200$
- $80 \times 6 = 480$
Add them:
$$
48,000 + 1,200 = 49,200 \\
49,200 + 480 = 49,680
$$
✔ Answer: The total number of eggs ordered in 6 months =
49,680 eggs

✔ Final Answers:
1.
19,880 sets of kitchen utensils
