How many times is the storage capacity of a DVD more than that of CD-R...

To find out how many times the storage capacity of a DVD is more than that of a CD-ROM, we can compare their storage capacities.
The storage capacity of a standard DVD is 4.7 gigabytes (GB), while the storage capacity of a standard CD-ROM is 700 megabytes (MB).
To calculate the difference in storage capacity, we can use the following formula:
Difference = DVD capacity - CD-ROM capacity
Difference = 4.7 GB - 700 MB
Converting GB to MB:
1 GB = 1024 MB
4.7 GB = 4.7 * 1024 MB = 4812.8 MB
Now, we can calculate the difference:
Difference = 4812.8 MB - 700 MB
Difference = 4112.8 MB
The storage capacity of a DVD is 4112.8 MB more than that of a CD-ROM.
To find out how many times the storage capacity of a DVD is more than that of a CD-ROM, we can divide the storage capacity of the DVD by the storage capacity of the CD-ROM:
Times = DVD capacity / CD-ROM capacity
Times = 4812.8 MB / 700 MB
Times = 6.875
Therefore, the storage capacity of a DVD is approximately 6.875 times more than that of a CD-ROM.
So, the correct answer is C: 25.
