Understanding Inverse Operations

Inverse operations are pairs of mathematical operations that undo each other. For example, addition and subtraction are inverse operations, as are multiplication and division. In this article, we will explore how to use inverse operations to verify equations.

The Importance of Verifying Equations

Verifying equations is a crucial step in mathematics. It helps to ensure that the equation is true and that the solution is correct. Inverse operations can be used to verify equations by checking if the result of the inverse operation is equal to the original value.

The Question

The question asks us to select the best answer for the following equation:

102 \div 3=34

Analyzing the Options

Let's analyze each option to determine which one is the best answer.

Option A: $$34 \times 3=102$$

This option involves multiplying 34 by 3. However, the original equation involves dividing 102 by 3, not multiplying 34 by 3. Therefore, this option is not the best answer.

Option B: $$34-3=31$$

This option involves subtracting 3 from 34. However, the original equation involves dividing 102 by 3, not subtracting 3 from 34. Therefore, this option is not the best answer.

Option C: $$102 \div 34=3$$

This option involves dividing 102 by 34. However, the original equation involves dividing 102 by 3, not 34. Therefore, this option is not the best answer.

Option D: $$34 \times 3=102$$

This option involves multiplying 34 by 3. However, the original equation involves dividing 102 by 3, not multiplying 34 by 3. Therefore, this option is not the best answer.

The Correct Answer

However, we can see that the correct answer is actually not listed among the options. The correct answer is the inverse operation of division, which is multiplication. Therefore, the correct answer is:

102 \div 3=34

is equivalent to:

34 \times 3=102

Conclusion

In conclusion, inverse operations can be used to verify equations by checking if the result of the inverse operation is equal to the original value. The correct answer is the inverse operation of division, which is multiplication.
