The image you've uploaded is a
math worksheet titled "Multiplication Problems 3.2A Answers" from
Math-Salamanders.com, which provides solutions to a series of word problems involving multiplication and division. Let's go through each problem, verify the answers, and explain the reasoning behind them.

1) A ream (500 sheets) of paper is 4 cm thick. How thick would 5 reams be?
Answer:
$ 4 \times 5 = 20 $ cm thick
✔ Explanation:
If one ream is 4 cm thick, then 5 reams would be 5 times as thick.
So:
$ 4 \text{ cm} \times 5 = 20 \text{ cm} $

2) You get 6 apples in a bag. How many apples in 2 bags?
Answer:
$ 6 \times 2 = 12 $ apples
✔ Explanation:
Each bag has 6 apples. For 2 bags:
$ 6 \times 2 = 12 $ apples
---
3) I share 12 chocolates equally between my 3 friends. How many chocolates do they each get?
Answer:
$ 12 \div 3 = 4 $ chocolates each
*Trick question – this is a division problem*
✔ Explanation:
This is indeed a
division problem because we're splitting 12 chocolates
equally among 3 people.
So:
$ 12 \div 3 = 4 $ chocolates per friend
> Note: The hint says it’s a "trick" because even though the worksheet is about multiplication, this one requires division.

4) A pen costs $5 to buy. How much would 4 pens cost?
Answer:
$ \$5 \times 4 = \$20 $
✔ Explanation:
Each pen is $5. For 4 pens:
$ 5 \times 4 = 20 $ dollars
---
5) A PP9 battery has 9 volts. If I connect 2 batteries together, how many volts would the circuit have?
Answer:
$ 9 \times 2 = 18 $ volts
✔ Explanation:
When batteries are connected in
series, their voltages add up.
So:
$ 9 \text{ V} + 9 \text{ V} = 18 \text{ V} $
Or: $ 9 \times 2 = 18 $ volts
> Note: This assumes series connection — standard for such problems unless otherwise stated.

6) How many legs would 4 cats have?
Answer:
$ 4 \times 4 = 16 $ legs
✔ Explanation:
Each cat has 4 legs. So:
$ 4 \text{ cats} \times 4 \text{ legs/cat} = 16 \text{ legs} $
---
7) Tyger downloads 3 new apps a week for his tablet. How many apps will he have after 3 weeks?
Answer:
$ 3 \times 3 = 9 $ apps
✔ Explanation:
He downloads 3 apps per week. Over 3 weeks:
$ 3 \text{ apps/week} \times 3 \text{ weeks} = 9 \text{ apps} $
---
✔ Summary of Key Concepts:
-
Multiplication is used when scaling quantities (e.g., more reams, more bags, more cats).
-
Division is used when sharing equally (as in Problem 3).
- Real-world context matters (e.g., voltage adds in series, not multiplies).
- Some problems may seem like multiplication but require division (trick questions).
