What is the ratio of 7,200 volts to 240 volts?

To determine the ratio of 7,200 volts to 240 volts, you can simply divide the larger number by the smaller number.

When you calculate this, you perform the following operation:

7,200 volts ÷ 240 volts = 30.

This result indicates that for every 30 units of the lower voltage (240 volts), there is 1 unit of the higher voltage (7,200 volts). Therefore, the ratio can be expressed as 30:1.

This is why the correct answer is the option that states the ratio is 30:1. Understanding this method of calculating ratios is essential for comparing different voltage levels correctly in electrical systems and applications.
