This page is designed to help students, parents, and teachers master the topic of division, quotients, and remainders through carefully selected practice questions and step-by-step solutions with explanations. Each solution provides the reasoning behind every step, helping learners build a strong foundation in arithmetic and problem-solving.
Problem: \(456 \div 6\)
Explanation: Divide 45 by 6, which gives 7 with a remainder of 3. Bring down the 6 to make 36. Then divide 36 by 6, which gives 6.
\(456 \div 6 = 76\). Therefore, the correct option is B.
Problem: \(2 \div 0\)
Explanation: Division by zero is undefined in mathematics because no number multiplied by 0 can equal 2.
Therefore, the correct option is D (division by zero is NOT allowed).
Problem: \(223 \div 1\)
Explanation: Any number divided by 1 remains equal to itself.
\(223 \div 1 = 223\). Therefore, the correct option is A.
Problem: Find quotient and remainder for \(547 \div 4\)
Explanation: Divide 547 by 4: \(4 \times 136 = 544\). Subtract 544 from 547 to get the remainder: \(547 - 544 = 3\).
Thus, \(q = 136\) and \(r = 3\). Therefore, the correct option is C.
Problem: \((21 + 5) \div (4 - 2)\)
Explanation: First evaluate expressions inside parentheses:
\(21 + 5 = 26\) and \(4 - 2 = 2\)
Then divide the results: \(26 \div 2 = 13\). Therefore, the correct option is A.
Problem: \((25 \div 5) \div (6 - 1)\)
Explanation: Evaluate parentheses first:
\(25 \div 5 = 5\) and \(6 - 1 = 5\)
Then divide: \(5 \div 5 = 1\). Therefore, the correct option is B.
Problem: \(64 \div 8\)
Explanation: Divide the total number of sweets by the number of sweets per box: \(64 \div 8 = 8\).
Therefore, the correct option is C.
Problem: Find the remainder of \(145 \div 6\)
Explanation: Divide 145 by 6: \(6 \times 24 = 144\). The remainder is \(145 - 144 = 1\).
Therefore, the correct option is D.
