Which of the following is equal to 3 * 9?

Rationale

9 * 3 is equal to 3 * 9.

In multiplication, the order of the numbers being multiplied does not change the result. Therefore, 9 * 3 is mathematically equivalent to 3 * 9, both resulting in the same product of 27.

A (6 * 6) YOUR ANSWER

This choice calculates the product of 6 * 6, which equals 36. While this multiplication is valid, it does not represent the same operation as 3 * 9, making it an incorrect option.

B (9 * 3) CORRECT

The multiplication of 9 * 3 yields 27, which is equivalent to 3 * 9. This choice correctly identifies the commutative property of multiplication, where changing the order of the factors does not change the outcome.

C (3 * 3 * 6) YOUR ANSWER

By multiplying 3 * 3 * 6, the result is 54. This expression does not match the multiplication of 3 * 9 and is therefore not equal to the original calculation.

D (3 * 3 * 3 * 3) YOUR ANSWER

Calculating 3 * 3 * 3 * 3 gives the product of 81. While this multiplication is accurate, it does not represent the same mathematical operation as 3 * 9, making it an incorrect choice.

Conclusion

The correct answer is B, as 9 * 3 is equal to 3 * 9 due to the commutative property of multiplication. Understanding this property allows for the recognition that the order of the factors can be rearranged without changing the final result, making these expressions equivalent in value.

Which of the following is equal to 3 * 9?
