2. a) how many milliseconds (ms) are in 1 second? 1. b) how many microseconds (μs) are in 1 second? 2. c) how many nanoseconds (ns) are in 1 millisecond? 3. d) how many microseconds are in 1 millisecond? 4. e) how many nanoseconds are in 1 microsecond? 5. f) how many kilobytes (kb) are in 1 gigabyte (gb)? 6. g) how many kilobytes are in 1 megabyte (mb)? 7. h) how many megabytes are in 1 gigabyte? 8. i) how many bytes are in 20 megabytes? 9. j) how many kilobytes are in 2 gigabytes?

Answer and explanation:

a) How many milliseconds (ms) are in 1 second?

1 second = 1000 milliseconds

1 second = milliseconds

b) How many microseconds (μs) are in 1 second?

1 second = 1000000 microseconds

1 second =   microseconds

c) How many nanoseconds (ns) are in 1 millisecond?

1 millisecond = 1000000 nanoseconds

1 millisecond =   nanoseconds

d) How many microseconds are in 1 millisecond?

1 millisecond = 1000 microseconds

1 millisecond =   microseconds

e) How many nanoseconds are in 1 microsecond?

1 microsecond = 1000 nanoseconds

1 microsecond = nanoseconds

f) How many kilobytes (KB) are in 1 gigabyte (GB)?

1 gigabyte = 1000000 kilobytes

1 gigabyte = kilobytes

g) How many kilobytes are in 1 megabyte (MB)?

1 megabyte = 1000 kilobytes

1 megabyte = kilobytes

h) How many megabytes are in 1 gigabyte?

1 gigabyte = 1000 megabytes

1 gigabyte = megabytes

i) How many bytes are in 20 megabytes?

1 megabytes = 1000000 bytes

20 megabytes = 20000000 bytes

20 megabytes = bytes

j) How many kilobytes are in 2 gigabytes?

1 megabyte = 1000 kilobytes

2 megabyte = 2000 kilobytes

2 megabyte =    kilobytes

the answer is c. 23/3
