Question: 1 / 400

How can kilometers be converted to miles according to the given conversion method?

Multiply by 5 and add 5

Multiply by 10 and drop the last digit

Multiply by 6 and drop the last digit

To convert kilometers to miles, the method involves using a common approximation for this specific conversion. The correct approach from the options is to multiply the number of kilometers by 6 and then drop the last digit. This method simplifies the conversion process by providing a quick estimate.

The rationale behind this approximation is based on the fact that 1 kilometer is approximately equal to 0.621371 miles. By multiplying by 6, you get a rough figure that is close to the actual equivalent in miles, since multiplying by 6 helps to emphasize whole number miles. Dropping the last digit serves as a way to simplify the result into a more manageable whole number, making it easier to understand and utilize in everyday contexts.

Using this method yields results that are fairly close to more precise calculations, making it practical for scenarios where a quick estimate is acceptable.
