+405 The table shows estimates of computer storage. A CD - ROM hold 700 MB. A DVD - ROM hold 4.7 GB. Estimate how many times more storage a DVD has than a CD. Explain how you found you answer. 1 kilobyte(KB) = 1000 bytes 1 megabyte(MB) = 1 million bytes 1 gigabyte(GB) = 1 billion bytes

It is nice to meet you :)
The table shows estimates of computer storage. A CD - ROM hold 700 MB. A DVD - ROM hold 4.7 GB. Estimate how many times more storage a DVD has than a CD. Explain how you found you answer. 1 kilobyte(KB) = 1000 bytes 1 megabyte(MB) = 1 million bytes 1 gigabyte(GB) = 1 billion bytes
CD 700MB
DVD 4.7GB = 4.7*1000 MB = 4700 MB
4700/700 = 47/7 = approx 6.71
So a DVD hold approx 6.71 times the amount of data that a CD holds
