i can answer this based on a senario.

Time taken to do a task by hand - 120 mins

Time taken to do a task by a machine - 10mins

Time saved - 110 mins

Time saved as a % = Total time saved/ Total time to do by hand X 100 %

time saved = 110/120 X100 %

= 91.66%

In other words, take the time saved as a fraction of the original time (ie divide it by the original time) and multiply by 100%.
