What is 51 divided by 3? A.) 17 B.) 25 C.) 24 D.) 21
The correct answer and explanation is:
Correct Answer: A.) 17
Explanation:
To solve 51 divided by 3, we are looking to determine how many times 3 fits into 51.
Step-by-step Division:
51÷3=?51 \div 3 = ?
Start by using long division or mental math:
- 3 goes into 5 once (3 × 1 = 3), remainder is 2.
- Bring down the 1 next to the 2, making it 21.
- 3 goes into 21 seven times (3 × 7 = 21), no remainder.
Thus: 51÷3=1751 \div 3 = 17
Why This Is Correct:
Division is one of the four basic arithmetic operations. It is essentially the process of repeated subtraction or finding how many equal groups of a number fit into another. In this case, we’re dividing 51 into 3 equal parts, and each part contains 17 units.
To verify, multiply the result by the divisor: 17×3=5117 \times 3 = 51
This confirms the result is accurate.
Eliminating Other Options:
- B.) 25:
25×3=7525 \times 3 = 75, which is too high. - C.) 24:
24×3=7224 \times 3 = 72, also too high. - D.) 21:
21×3=6321 \times 3 = 63, still higher than 51.
Only A.) 17 gives the exact product when multiplied by 3.
Real-world Application:
Imagine you have 51 apples and want to divide them equally among 3 friends. Each friend would get 17 apples. This is a practical use of division — equally sharing a quantity.
In summary, division helps break things into equal parts, and understanding it is essential in everyday tasks like budgeting, sharing, and problem-solving.
✔ Final Answer: A.) 17
