As in the last problem, bytes are a unit of measurement to measure memory in a computer.
To solve this question, the relationship between a kilobyte and a gigabyte must be solved; more precisely, the relationship between the kilo and giga factors.
Kilo is 10 3 and giga is 10 9. That is a difference of six powers of 10 or 10 6.
1 x 10 9 giga
_____________ = 1 x 10 6
1 x 10 3 kilo
From this ratio, we can see that there is a difference of six powers of 10, and since giga is larger than
kilo, there must be 100,000 (six places) kilobytes for every gigabyte.
1 gigabyte = 100,000 kilobytes
Now the second ratio of comparison can be set up for this question:
1 gigabyte 4 gigabytes
___________ = ____________
100,000 kilobytes x kilobytes
Cross multiply and solve for x:
x = (100,000) (4)
x = 400,000 kilobytes
4 gigabytes = 400,000 kilobytes
