Answer 1

To solve this equation, we can set up a proportion.
Let x represent the total space on the card.

We have the proportion:

1.2 GB / x = 8% / 100%

To solve for x, we can cross multiply:

1.2 GB * 100% = 8% * x

120 GB = 0.08x

Dividing both sides by 0.08, we get:

x = 120 GB / 0.08

x = 1500 GB

Therefore, the total space on the card was 15 GB.

The correct answer is 15 GB.
