Question

In 2012 a survey found that 92% of people in the 18 to 29 age group used social networking sites

a.Express the percent as a rate per 100.
b.what is this percent written as a fraction

Answer 1

Percents are parts of 100, so we can write 92 as a fraction over 100.

92/100

Simplify:

23/25

Answer 2

A)
That means 92 people out of 100 in the age group of 18 to 29 use social networking sites.

So as a rate, it would be 92 out of 100.
B)

`\sf x`%
`\sf =(x)/(100)`

So then
`\sf 92`%
`\sf= (92)/(100)`
