Hi Armygirl   I have been getting ready for my teas test, and your question is on one of the flash cards I made myself. Hopefully I can explain this clearly. Think of setting up a algebra problem.


  14 is what % of 35===    14=35X ==== 14/35=X  === .4=X    now multiply .4 by 100 to get 40 so the answer is 40%


 


16 is what  % of 20== 16=20X ==== 16/20=X ==.8=X  ===   .8x100= 80%


   Hope this helps good luck on your test.

   Usually, there's more than one way to solve arithmetic and math problems.


   The following may be easier to work with and remember:


   14/35  =   .4 , but since you want percent, you must multiply .4 times 100, which equals 40%.


   Yet more briefly,


   16/20  =   .8


   .8 X 100  =  80%


   Still more briefly,


   16/20 X 100  =  80%


   Textbooks rarely explain that percentage means "parts per hundred," and that percentage is a conversion--it converts a fraction, decimal, or another number to parts per hundred.


   Supposedly, it's easier for us to understand parts per hundred than the equivelant decimal, fraction, or number.


   What's your opinion? I believe most of us are pretty comfortable with the idea that, for instance, 16 is only part of 20, and we can represent that portion as a decimal,  .8 , or that 20 is one part of 20, and we can represent that portion as 1.
