Question

The proportion of the memory space of a flash drive that is unused is 3 by 8.
There are 40 gigabytes of used memory. What is the total capacity of the drive?

Answer 1

Answer:

Let total capacity of the drive be x.

Unused memory space =3/8 of x

.: used memory space = 5/8 of x

40 = 5/8x

40✖️8 /5 = x

x = 64 gigabytes

Therefore, total capacity of the drive is 64 gigabytes.
