Memory on electronic storage devices is measured in bytes, or in larger units such as kilobytes (kB), megabytes (MB), or gigabytes (GB). Suppose a floppy disk has a memory capacity of 1440 kB.
a - If a CD (compact disc) has a memory capacity of 600 MB, then compared to the floppy, how many times as much memory capacity does the CD have?
b - If a DVD (digital video disc or digital versatile disc) has a memory capacity of 4.7 GB, then compared to the CD, how many times as much memory capacity does the DVD have?
i would really appreciate the help...thanks so much!!!

a. approx. 416.66 times the floppy disk. (600mb = 600 000kb)
b. approx. 7.83 times the CD (4.7GB = 4700mb)

k = 1000 and M = 1000000 so 1000 kB = 1 Mb and 600 Mb = 600 x 1000 or 600000 Kb. Divide 600000 by 1440 and you'll get it.

a) 600/1.44 = 416.67 times
b) 4.7/.6 = 7.83 times
