A digital memory card is only 8% full. If there is 1.2 GB worth of data on the card, how much data is remaining?

Answer 1

To solve this problem, we need to use a proportion:

Let x be the amount of data remaining.

8% = 0.08 as a decimal is the proportion of the card that is full.

0.08 = 1.2 GB / x

To solve for x, we can cross-multiply and simplify:

0.08x = 1.2 GB

x = 1.2 GB / 0.08

x = 15 GB

Therefore, the amount of data remaining on the memory card is 15 GB.
