Calculate percentage!?

I have 108,862 total who were surveyed. 34,048 completed college, and 19,102 completed a bachelors degree. How do i calculate the percentage?Calculate percentage!?
Completed college:

= 100%(34,048/108,862)

= 100%(17,024/54,431)

= 1,702,400/54,431%

= 31 15,039/54,431%



Answer: 31% completed college

-----------

Completed a bachelors degree:

= 100%(19,102/108,862)

= 100%(9,551/54,431)

= 955,100/54,431% or 17 29,773/54,431%



Answer: 18% completed a bachelors degreeCalculate percentage!?
There are 3 pieces of information in percentage problems: Rate, Part, Whole



Rate is related to % as follows:



% = 100 * Rate



If you know the Rate, multiply by 100 to get the corresponding %



If you know the %, divide by 100 to get the Rate



The following diagram shows the percentage problem arithmetic:



Part

------------------

Whole * Rate



If you know the Rate and the Whole, multiply them to get the Part



If you know the Rate and the Part, divide the Part by the Rate to get the Whole



If you know the Part and the Whole, divide the Part by the Whole to get the Rate



----------------------------



34,048 as percentage of 108,862



Whole = 108,862



Part = 34,048



Rate = 34048/108862 = .3127



% = 100(.3127) = 31.27 or 31% rounded completed college



100(19102/108862) = 18% rounded completed bachelors degreeCalculate percentage!?
Depends what percentage you are trying to calculate.



34,048/108,862 x 100 = 31.3% completed college

19,102/34,048 x 100 = 56.1% of those who completed college have a bachelors degree

19,102/108,862 x 100 = 17.5% of the total surveyed have a bachelors degree
