Let's solve each of the multiplication word problems step by step and identify the "trick" problem that is not a multiplication problem.
---
Problem 1:
An insect has 6 legs. How many legs do 5 insects have?
- Each insect has 6 legs.
- There are 5 insects.
- Total legs = \( 6 \times 5 = 30 \).
Answer: 30 legs.
---
Problem 2:
How many legs do 10 tables have?
- Tables do not have legs in the biological sense. This is a trick question because it is not a multiplication problem involving living creatures with legs.
- If we assume the question is asking about the number of table legs (which is typically 4 per table):
- Total legs = \( 4 \times 10 = 40 \).
- However, since the question does not specify that tables have legs, this is the "trick" problem.
Answer: Not applicable as a multiplication problem.
---
Problem 3:
A tablet takes 3 hours to fully charge. How many hours would it take to charge 6 tablets one after the other?
- Each tablet takes 3 hours to charge.
- Charging 6 tablets one after the other means the total time is:
- Total time = \( 3 \times 6 = 18 \) hours.
Answer: 18 hours.
---
Problem 4:
There are 4 seasons in a year. How many seasons in 6 years?
- Each year has 4 seasons.
- In 6 years, the total number of seasons is:
- Total seasons = \( 4 \times 6 = 24 \).
Answer: 24 seasons.
---
Problem 5:
Captain catches 10 frogs but 8 of them escape. How many are left?
- Captain catches 10 frogs.
- 8 frogs escape.
- Frogs left = \( 10 - 8 = 2 \).
- This is a subtraction problem, not a multiplication problem.
Answer: 2 frogs.
---
Problem 6:
I buy 6 packs of ten pens. How many pens have I bought?
- Each pack contains 10 pens.
- There are 6 packs.
- Total pens = \( 10 \times 6 = 60 \).
Answer: 60 pens.
---
Problem 7:
Newton can run 3 meters in a minute. How far could he run in 10 minutes?
- Newton runs 3 meters per minute.
- In 10 minutes, the total distance is:
- Total distance = \( 3 \times 10 = 30 \) meters.
Answer: 30 meters.
---
Problem 8:
Eggs come in boxes of 6. How many eggs in 10 boxes?
- Each box contains 6 eggs.
- There are 10 boxes.
- Total eggs = \( 6 \times 10 = 60 \).
Answer: 60 eggs.
---
Identifying the Trick Problem:
The trick problem is
Problem 2, which asks about the number of legs on 10 tables. Since tables do not have biological legs, this is not a valid multiplication problem involving living creatures with legs. Additionally,
Problem 5 is a subtraction problem, not a multiplication problem.
---
Final Answer:
\[
\boxed{2}
\] (Problem 2 is the trick problem.)
