- Multiplicative Comparison and Number Patterns
- 10 questions
- 12 minutes
These questions practice comparing with multiplication, like "4 times as long", and extending patterns from a rule. Tip: "times as many" means multiply or divide, while "how many more" means subtract.

Question 1
Which equation shows "35 is 5 times as many as 7"?
Correct answer: D
"5 times as many as 7" means 5 × 7, and that equals 35. 35 = 5 + 7 adds the numbers instead of multiplying, and 5 + 7 is only 12.

Question 2
A red ribbon is 6 inches long. A blue ribbon is 4 times as long as the red ribbon. How long is the blue ribbon?
Correct answer: A
4 times as long means 4 × 6 = 24 inches. 10 inches adds 4 instead of multiplying by 4.

Question 3
Ana has 48 stamps. That is 8 times as many stamps as Ben has. How many stamps does Ben have?
Correct answer: C
Ben has the smaller amount, so divide: 48 ÷ 8 = 6. 384 multiplies, which would give Ben more stamps than Ana.

Question 4
How many times as many is 63 as 9?
Correct answer: B
9 × 7 = 63, so 63 is 7 times as many as 9. 54 is how many more, found by subtracting.
-
Question 5
A pattern starts at 4, and the rule is "add 6": 4, 10, 16, 22, … What is the 6th number in the pattern?
Correct answer: D
Keep adding 6: 4, 10, 16, 22, 28, 34. 28 is the 5th number, not the 6th.
-
Question 6
A pattern starts at 3, and the rule is "add 5". Which statement about the numbers in the pattern is true?
Correct answer: B
The pattern is 3, 8, 13, 18, 23, … Adding an odd number changes odd to even and even to odd, so the numbers take turns.
-
Question 7
What number comes next in this pattern?
3, 6, 12, 24, ☐Correct answer: C
Each number is double the one before, so the next number is 24 × 2 = 48. 30 adds 6, but the pattern does not add the same amount each time.
-
Question 8
What number is missing from this pattern?
5, 9, 13, ☐, 21Correct answer: A
The rule is "add 4": 13 + 4 = 17, and 17 + 4 = 21 checks.
-
Question 9
Tom has 4 marbles. Sue has 3 times as many marbles as Tom. How many more marbles does Sue have than Tom?
Correct answer: D
Sue has 3 × 4 = 12 marbles, and 12 - 4 = 8 more than Tom. 12 is how many Sue has, not how many more.
-
Question 10
Figure 1 of a pattern has 5 squares. Each new figure has 4 more squares than the one before. How many squares are in Figure 6?
Correct answer: A
Figure 1 has 5, then 9, 13, 17, 21, and Figure 6 has 25. From Figure 1 to Figure 6 there are 5 steps of 4: 5 + 20 = 25. 21 is Figure 5.
