17. 0.4 / 0.04 =

Answer: B

Explanation:

0.4 / 0.04 = 10

Dividing 0.4 by 0.04 results in 10, as this calculation simplifies to 10 when expressed as a fraction or performed directly.

A) 100

Option A is incorrect because dividing 0.4 by 0.04 does not yield 100. In fact, 0.4 is ten times greater than 0.04, which indicates that the quotient must be 10, not 100.

B) 10

Option B is correct. When performing the division of 0.4 by 0.04, one can rewrite the operation as 0.4 / 0.04 = 10, confirming that this is the accurate result.

C) 0.1

Option C is incorrect as it represents a value significantly less than the actual quotient. Dividing 0.4 by 0.04 cannot yield a result of 0.1 because 0.4 is much larger than 0.04, leading to a larger quotient.

D) 0.01

Option D is also incorrect. This option suggests an even smaller value that is not reflective of the division performed. Since 0.4 is much greater than 0.04, the result cannot be as low as 0.01.

Conclusion

The correct answer is 10, as derived from the division of 0.4 by 0.04. All other options fail to represent the proper calculation, demonstrating a misunderstanding of the relationship between the numerator and denominator in this arithmetic operation.
