\n" ); document.write( "Part/Whole = %/100 [Formula for percent]
\n" ); document.write( "x/40=32/100 [Plug-in the values]
\n" ); document.write( "100x=(40)(32) [Cross-multiply]
\n" ); document.write( "100x=128 [Solve for x]
\n" ); document.write( "100x/100=128/100
\n" ); document.write( "x=$12.8
\n" ); document.write( ".
\n" ); document.write( "Check by plugging all of the values back into the formula for percent
\n" ); document.write( "12.8/40=32%/100
