Answer:
Number of CDs = 7
Explanation:
We know that
1 GB = 1024 MB
So it means the 4 GB of data can be interpreted as:
4 GB = 1024*4 MB
4GB = 4096 MB
So a DVD hold 4096 MB of data while a CD holds 650 MB of data.
We need to find how many CDs could hold 4096 MB of data, to make it equivalent to a DVD
Number of CDs = 4096/650
Number of CDs= 6.3
As a CD can not be 0.3, a whole 1 CD will be used.
Number of CDs = 7
