What is 15 divided by 3?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (D)

To find the result of dividing 15 by 3, you need to determine how many times the number 3 can fit into 15. This process is known as division, which essentially reverses multiplication. If you can multiply a number by 3 to get 15, you've completed the division accurately.

In this case, multiplying 3 by 5 gives you 15 (3 × 5 = 15). Therefore, when you divide 15 by 3, the answer is 5, indicating that 3 can fit into 15 exactly five times without any remainder.

Understanding division in this manner allows students to grasp the concept more clearly, as it ties back to their knowledge of multiplication. When students think of division as finding how many groups of a certain size can be made from a total, they build a stronger foundation in mathematics. This principle highlights the relationship between multiplication and division, crucial for their overall mathematical education.
