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? (1 point)
○ 15 GB
○ 10.5 GB
1.05 GB
○ 13.8 GB
To find the total space on the memory card, we can set up a proportion using the amount of data that is 8% full:
Let x be the total space on the memory card.
1.2 GB is 8% of x.
1.2/x = 8/100
Cross multiply:
8x = 120
Divide by 8 on both sides:
x = 120/8 = 15
Therefore, the total space on the memory card is 15 GB.
So, the correct answer is:
○ 15 GB
