Answer:
The shortcuts is
Divide number of units by 100
Step-by-step explanation:
From the question we are told that
insulin u-100 is 
From the data given above we see that
100 units of insulin u-100 is contained in 1 mL
So 1 unit of u-100 is contained in x mL
=> 
This means that a unit of insulin u-100 occupies 
So we can represent a single unit of insulin u-100 as 
Now if 1 unit of insulin u-100 is represented as 
Then y unites of insulin u-100 is represented as z
So

From the above calculation we can see that the shortcuts to convert u-100 insulin given in units, to mL is to divide number of units by 100
