Respuesta :

To find the percentages that they ask us, we must first know 100%, that is, the number of people surveyed:

[tex]5+55+45+145=250[/tex]

250 as the statement says.

what percentage of the people exercise regularly?

People who exercise regularly are 5 + 55 = 60

If 250 is 100%, then 60 must be 24%.

24% of the people exercise regularly.

What percentage of the people smoke?

People who smokes are 5 +45 = 50.

If 250 is 100%, then 50% must be 20%.

20% of the surveyed people smoke.
