How many nanoseconds does it take for a computer to perform one calculation if it performs 6.7 × 10^{7} calculations per second?

the comuter does 1 calculation in 1.5* nanosec

Step-by-step explanation:

First step: we need to write all terms in nanosec, as we know:

1[nanosec]= [sec]

The computer does 6.7* []

if we multiplicate for , from the units convertion.

6.7* [ *

6.7* []

Now doing a simple three rule we have this:

6.7 * calculation in ⇒ 1 nanosec

1 calculation in ⇒

So, we found: the comuter does 1 calculation in 1.5* nanosec
