# Division of Multiples of 10, 100, and 1,000 By 1-Digit Numbers
Section A: Multiple Choice Questions
Q1: What is 80 ÷ 4? (a) 2 (b) 20 (c) 200 (d) 40
Solution:
Ans: (b) 20 Explanation: To divide 80 by 4, we can think of it as 8 tens ÷ 4. Since \(8 \div 4 = 2\), we have \(8\) tens \(\div 4 = 2\) tens, which equals 20.
Q2: What is 300 ÷ 5? (a) 6 (b) 60 (c) 600 (d) 50
Solution:
Ans: (b) 60 Explanation: We can rewrite 300 as 30 tens. Then \(30 \div 5 = 6\), so \(30\) tens \(\div 5 = 6\) tens = 60. Alternatively, \(300 \div 5 = 60\).
Q3: Which equation shows the correct way to divide 6,000 by 3? (a) \(6 \div 3 = 2\), so \(6{,}000 \div 3 = 200\) (b) \(6 \div 3 = 2\), so \(6{,}000 \div 3 = 2{,}000\) (c) \(6 \div 3 = 3\), so \(6{,}000 \div 3 = 3{,}000\) (d) \(6 \div 3 = 2\), so \(6{,}000 \div 3 = 20\)
Solution:
Ans: (b) \(6 \div 3 = 2\), so \(6{,}000 \div 3 = 2{,}000\) Explanation: Since \(6 \div 3 = 2\), we can use the basic fact and keep the number of zeros the same. 6,000 has three zeros, so the answer is 2,000. Option (a) has the wrong number of zeros, and option (c) uses an incorrect basic fact.
Q4: What is 4,200 ÷ 7? (a) 60 (b) 600 (c) 6 (d) 6,000
Solution:
Ans: (b) 600 Explanation: We can think of 4,200 as 42 hundreds. Since \(42 \div 7 = 6\), we have \(42\) hundreds \(\div 7 = 6\) hundreds = 600.
Q5: A student solved 240 ÷ 6 and got 4. What mistake did the student make? (a) The student forgot to add a zero to the answer (b) The student used the wrong basic fact (c) The student divided incorrectly (d) The student multiplied instead of divided
Solution:
Ans: (a) The student forgot to add a zero to the answer Explanation: The correct answer is 40. Since \(24 \div 6 = 4\), and 240 has one zero, the answer should be \(4\) with one zero, which is 40. The student likely forgot to include the zero from 240.
Q6: What is 5,600 ÷ 8? (a) 70 (b) 700 (c) 7 (d) 7,000
Solution:
Ans: (b) 700 Explanation: We can rewrite 5,600 as 56 hundreds. Since \(56 \div 8 = 7\), we have \(56\) hundreds \(\div 8 = 7\) hundreds = 700.
Q7: Which of these division problems has a quotient of 90? (a) 270 ÷ 3 (b) 180 ÷ 3 (c) 450 ÷ 5 (d) 360 ÷ 6
Q8: What is 7,200 ÷ 9? (a) 8 (b) 80 (c) 800 (d) 8,000
Solution:
Ans: (c) 800 Explanation: We can think of 7,200 as 72 hundreds. Since \(72 \div 9 = 8\), we have \(72\) hundreds \(\div 9 = 8\) hundreds = 800.
Section B: Fill in the Blanks
Q9: When dividing 600 by 2, we can use the basic fact \(6 \div 2 = 3\) and place __________ zeros after the 3 to get the answer.
Solution:
Ans: two (or 2) Explanation: Since 600 has two zeros, and the basic fact gives us 3, we keep the two zeros to get 300.
Q10: The quotient of 3,600 ÷ 4 is __________.
Solution:
Ans: 900 Explanation: We can rewrite 3,600 as 36 hundreds. Since \(36 \div 4 = 9\), the answer is \(9\) hundreds = 900.
Q11: When we divide 8,000 by 8, we get __________.
Solution:
Ans: 1,000 Explanation: Since \(8 \div 8 = 1\), and 8,000 has three zeros, the quotient is \(1\) with three zeros = 1,000.
Q12: The division problem 540 ÷ 6 can be solved using the basic fact __________ ÷ 6 = 9.
Solution:
Ans: 54 Explanation: We can think of 540 as 54 tens. Using the basic fact \(54 \div 6 = 9\), we find that \(540 \div 6 = 90\).
Q13: If 42 ÷ 7 = 6, then 4,200 ÷ 7 = __________.
Solution:
Ans: 600 Explanation: We use the basic fact \(42 \div 7 = 6\) and keep the same number of zeros. Since 4,200 has two zeros, the answer is 6 with two zeros = 600.
Q14: The value of 1,800 ÷ 3 is __________.
Solution:
Ans: 600 Explanation: We can rewrite 1,800 as 18 hundreds. Since \(18 \div 3 = 6\), the answer is \(6\) hundreds = 600.
Section C: Word Problems
Q15: A library has 360 books to arrange equally on 4 shelves. How many books will be on each shelf?
Solution:
Ans: We need to divide 360 by 4. Think of 360 as 36 tens. \(36 \div 4 = 9\) So \(36\) tens \(\div 4 = 9\) tens = 90 Final Answer: 90 books
Q16: A factory produces 4,500 toy cars in one day. The cars are packed equally into 5 trucks for delivery. How many toy cars are in each truck?
Solution:
Ans: We need to divide 4,500 by 5. Think of 4,500 as 45 hundreds. \(45 \div 5 = 9\) So \(45\) hundreds \(\div 5 = 9\) hundreds = 900 Final Answer: 900 toy cars
Q17: A school has 2,400 pencils to distribute equally among 6 classrooms. How many pencils will each classroom receive?
Solution:
Ans: We need to divide 2,400 by 6. Think of 2,400 as 24 hundreds. \(24 \div 6 = 4\) So \(24\) hundreds \(\div 6 = 4\) hundreds = 400 Final Answer: 400 pencils
Q18: A farmer collected 6,300 eggs and wants to pack them equally into 7 crates. How many eggs will go in each crate?
Solution:
Ans: We need to divide 6,300 by 7. Think of 6,300 as 63 hundreds. \(63 \div 7 = 9\) So \(63\) hundreds \(\div 7 = 9\) hundreds = 900 Final Answer: 900 eggs
Q19: A bakery baked 720 cookies and packed them equally into 8 boxes. How many cookies are in each box?
Solution:
Ans: We need to divide 720 by 8. Think of 720 as 72 tens. \(72 \div 8 = 9\) So \(72\) tens \(\div 8 = 9\) tens = 90 Final Answer: 90 cookies
Q20: A charity organization collected 8,100 canned goods to divide equally among 9 food banks. How many canned goods will each food bank receive?
Solution:
Ans: We need to divide 8,100 by 9. Think of 8,100 as 81 hundreds. \(81 \div 9 = 9\) So \(81\) hundreds \(\div 9 = 9\) hundreds = 900 Final Answer: 900 canned goods
