How can a frequency in megahertz be stated in gigahertz?
- ADivide by 1 000
- BMultiply by 1 000
- CDivide by 1 000 000
- DMultiply by 1 000 000
Correct answer: A — Divide by 1 000. From the official ISED question bank, verified word for word.
Why
To change a frequency from megahertz to gigahertz, you must divide by 1 000 because a gigahertz is a larger unit containing one thousand megahertz. The full explanation — and one for every question — is in Pro.
