A digital memory card is only 8% full. If there is 1.2 GB worth of data, how much total space was on the card?
A. 15 GB
B. 10.5 GB
C. 13.8 GB
D. 1.05 GB
To find the total space on the memory card, we can set up a proportion:
1.2 GB is 8% of the total space on the memory card.
1.2/x = 8/100
Cross multiply:
8x = 120
Now, divide by 8 on both sides:
x = 15
Therefore, the total space on the memory card is 15 GB.
The correct answer is A. 15 GB
