Divide: 18 ?â?À 0.12 =
Correct answer
A
Rationale
To divide 18 by 0.12, we can convert the divisor to a whole number by moving the decimal point two places to the right, making it 12. Now, we perform the division 18 ?À 12 = 1.5. However, since we initially moved the decimal point in the divisor, we must move it back in the quotient to get the final answer of 150.
Choice A is correct (150) because it correctly follows the steps of dividing 18 by 0.12 and adjusting for the decimal point.
Choices B, C, and D are incorrect because they do not accurately represent the result of dividing 18 by 0.12 using the correct decimal manipulation. Choice B (180) is the result of a simple division of 18 by 0.12 without considering the decimal point adjustment. Choice C (15) and Choice D (16) are incorrect results obtained without the proper conversion of the decimal divisor.
