This grade 4 multiplicative worksheet answer key solves all 24 problems of the multiplicative comparison and multi-step problems worksheet step by step.
Each worked solution names the operation, shows the equation with its letter, and states the final answer in bold. Check your own work against every step, and notice whether a mistake came from choosing the wrong operation or from a calculation.
Grade 4 Multiplicative Worksheet Answer Key: problems 1–5
Problem 1: Read the equation
Four groups of 6 make 24, so 24 is 4 times as many as 6. It is also 6 times as many as 4.
Problem 2: Two sentences
Because \(5 \times 7 = 35\), the equation gives two sentences.
35 is 5 times as many as 7. 35 is 7 times as many as 5.
Problem 3: Write the equation
(a) \(18 = 3 \times 6\), which is true because \(3 \times 6 = 18\). (b) \(42 = 6 \times 7\), which is true because \(6 \times 7 = 42\).
Problem 4: Five times as many
\(5 \times 7 = 35\).
Answer: 35
Problem 5: Pencils
The larger amount is unknown, so multiply: \(4 \times 6 = 24\).
Answer: 24 pencils
Grade 4 Multiplicative Worksheet Answer Key: problems 6–10
Problem 6: Tall tree
\(5 \times 9 = 45\).
Answer: 45 feet
Problem 7: Find the unknown
The equation is \(6 \times n = 48\). Divide: \(n = 48 : 6 = 8\). Check: \(6 \times 8 = 48\).
Answer: \(n = 8\)
Problem 8: How many times
\(36 : 9 = 4\), because \(4 \times 9 = 36\).
Answer: 4 times as long
Problem 9: More than or times
(a) “More than” means add: \(5 + 7 = 12\). (b) “Times as many” means multiply: \(7 \times 5 = 35\).
Answer: (a) 12; (b) 35
Problem 10: Add or multiply
(a) “Longer than” compares by adding. (b) “Times as long” compares by multiplying. (c) “Shorter than” compares by subtracting, which is additive.
Answer: (a) adding; (b) multiplying; (c) adding (subtracting)
Grade 4 Multiplicative Worksheet Answer Key: problems 11–15
Problem 11: Pages read
\(3 \times 12 = 36\).
Answer: 36 pages
Problem 12: Stickers and a letter
\(7 \times s = 56\). Divide: \(s = 56 : 7 = 8\). Check: \(7 \times 8 = 56\).
Answer: 8 stickers
Problem 13: Bus and van
\(40 : 8 = 5\), because \(5 \times 8 = 40\).
Answer: 5 times as long
Problem 14: Pencils sold
\(8 \times p = 72\). Divide: \(p = 72 : 8 = 9\). Check: \(8 \times 9 = 72\).
Answer: 9 pencils
Problem 15: More and times
(a) Compare by adding: \(24 – 8 = 16\). (b) Compare by multiplying: \(24 : 8 = 3\), because \(3 \times 8 = 24\).
Answer: (a) 16 more; (b) 3 times as many
Grade 4 Multiplicative Worksheet Answer Key: problems 16–20
Problem 16: Two amounts together
Step 1: \(4 \times 9 = 36\) stickers for Sofia.
Step 2: \(9 + 36 = 45\).
Answer: 45 stickers
Problem 17: Estimate and solve
Estimate: \(60 \times 5 = 300\). Exact: \(5 \times 62 = 310\). The exact answer is close to the estimate, so it is reasonable.
Answer: about 300; exactly 310 beads
Problem 18: Savings by month
February: \(f = 3 \times 15 = 45\). March: \(m = 45 – 8 = 37\).
Answer: $37
Problem 19: Concert tickets
VIP ticket: \(4 \times 9 = 36\) dollars. Two child tickets: \(2 \times 9 = 18\) dollars. Total: \(36 + 18 = 54\).
Answer: $54
Problem 20: Marbles gift
Before the gift: \(m = 5 \times 6 = 30\). After the gift: \(30 – 8 = 22\).
Answer: 22 marbles
Grade 4 Multiplicative Worksheet Answer Key: problems 21–24
Problem 21: Runs scored
Lions: \(3 \times 7 = 21\). Eagles: \(21 – 4 = 17\). All three: \(7 + 21 + 17 = 45\).
Answer: 45 runs
Problem 22: Is it reasonable
Round 38 to 40. Then \(40 \times 7 = 280\), so the answer should be near 280. Noah’s 366 is much too large. Exact: \(7 \times 38 = 266\).
Answer: 266 chicks
Problem 23: Fruit stand
Oranges: \(o = 4 \times 25 = 100\). Pears: \(p = 100 – 15 = 85\). Total: \(25 + 100 + 85 = 210\).
Answer: 210 pieces of fruit
Problem 24: Beads and bags
Sofia’s beads: \(9 \times s = 72\), so \(s = 72 : 9 = 8\). New beads: \(5 \times 8 = 40\). Total: \(8 + 40 = 48\).
Answer: 48 beads
