How many megahertz is 7040 kHz?

In the metric system, the prefix 'kilo' (k) stands for one thousand (1,000), and 'mega' (M) stands for one million (1,000,000). This means that one megahertz is equal to 1,000 kilohertz. To convert a frequency from a smaller unit (kHz) to a larger unit (MHz), you must divide the value by 1,000. This is the equivalent of moving the decimal point three places to the left. Dividing 7040 by 1,000 gives you exactly 7.040. The distractors are incorrect because they represent shifting the decimal point by the wrong number of places or in the wrong direction.
