1 nanosecond = one ___
of a __

Answer 1

1 nanosecond = 1 billionth of a second

Explanation:

A nanosecond (ns) is an SI unit of time equal to one billionth of a second, that is, ​1⁄1 000 000 000 of a second, or 10^−9 seconds. The term combines the prefix nano- with the basic unit for one-sixtieth of a minute. A nanosecond is equal to 1000 picoseconds or ​1⁄1000 microsecond.

Answer 2

By definition,

1 nanosecond = one billionth of a second

In other words, it takes 1 billion nanoseconds to elapse for one whole second to pass by. It's a very small amount of time.
