To solve this problem we can use a proportion, difference/original=x/100.
\n" ); document.write( "Here, the difference means the number of increase or decrease between the original number and the new number. To find the difference you subtract 19.68-16.65, and get 3.03.
\n" ); document.write( "The original means the number before the increase or decrease, and the x/100 part will help you find the percent.
\n" ); document.write( "DIFFERENCE:3.03
\n" ); document.write( "ORIGINAL:16.65
\n" ); document.write( "Now using the new found information, we can plug it in the proportion.
\n" ); document.write( "3.03 x
\n" ); document.write( "---- = ------
\n" ); document.write( "16.65 100
\n" ); document.write( "From here you make an equation by cross multiplying, and get:
\n" ); document.write( "3.30(100)=16.65x ======> 303=16.65x (solve for x)\r
\n" ); document.write( "\n" ); document.write( "Try solving the problem now. The answer you get, will be the percent, so no need to move any decimal over :) \r
