there are 121 people who take grebex.
\n" ); document.write( "1 out of every 11 of them will experience undesirable side effects.
\n" ); document.write( "divide 121 by 11 to get 11.
\n" ); document.write( "11 * 1 = 11 people who would experience undesirable side effects.
\n" ); document.write( "11/121 = 1/11 when you simplify it, so the proportion holds.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if you let x = the number of people who experience bad side effects,then you get the ratio:
\n" ); document.write( "1/11 = x/121
\n" ); document.write( "cross multiply to get x = 121/11 which equals 11.
\n" ); document.write( "replace x with 11 and the ratio becomes:
\n" ); document.write( "1/11 = 11/121
\n" ); document.write( "cross multiply and you get 1*121 = 11*11 which results in 121 = 121.
\n" ); document.write( "this confirms that the ratio is good.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the other way to look at is:
\n" ); document.write( "1/11 = .090909091 which is equivalent so 9.090909091% of the people who take grebex will experience side effects.
\n" ); document.write( "9.090909091% of 121 = .09090909091 * 121 = 11.
\n" ); document.write( "your answer is that 11 people will experience side effects.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
