Answer:
20.75%
Step-by-step explanation:
Note(a build-up): An actual 100% hard drive space usage in this case would mean a total hard drive space usage
For example, to have an actual 100% hard drive space usage, it would mean the total hard drive space (16GB) must be used (i.e. 16GB = 16GB)
So, 16/16 × 100/1 = 100%
We solved the above using the formula below:
x = the actual drive space used by photos/the total hard drive space × 100/1
Let us get back to the original question:-
Given: There is a 16 GB hard drive and 3.32 GB is taken up by photos.
To find: The percentage of the actual hard drive space used by photos
Solution:
Let the expected percentage(%) be z
Where: the total hard drive space = 16GB = b
the actual hard drive space used = 3.32GB = a
So, we use the formula:
z = the actual hard drive space used by photos/the total drive space × 100/1
∴ z = a/b × 100/1
z = 3.32/16 × 100/1
z = 0.2075 × 100
z = 20.75%
