Answer:
95%
Explanation:
So, we can see on the chart that 78 out of 82 people from ages 18 to 22 use Face.book. So we're trying to find what percentage 78 is of 82:
The first step is to write 78 as a fraction of 82, which is:
78/82
In order to find the simplest form of 78/82 we cancel out the greatest common divisor of 78 and 82, which is 2 :
78/82 = 37/41
Now we just need to convert this fraction to a percentage :
37/41 = 95% (rounded)
So we have the final answer :
78 is 95% of 82
Which means that:
Approximately 95% of people from ages 18 to 22 use Face.book
