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

hope this helps:)
