14% means 14 out of 100, or the fraction \"14%2F100=0.14\".
\n" ); document.write( "To calculate 14% of an amount, multiply by \"0.14\" (It's \"14%2F100\" after all).
\n" ); document.write( "To increase an amount by 14%, multiply by \"1.14\" (It's \"%281%2B0.14%29\" times, one time the amount, plus the \"0.14\" times that indicates the 14% increase).
\n" ); document.write( "To decrease an amount by 14%, multiply by \"0.86\" (because you want one time the amount minus the 0.14 times the amount that indicates the 14% decrease, and \"1-0.14=0.86\")
\n" ); document.write( "£\"13\" increased by 10% is £\"13%2A1.10\"= £\"14.30\"
\n" ); document.write( "£\"900\" increased by 47% is £\"900%2A1.47\"= £\"1323\"
\n" ); document.write( "£\"99\" decreased by 30% is £\"99%2A0.70\"= £\"69.30\"
\n" ); document.write( "£\"350\" decreased by 25% is £\"350%2A0.75\"= £\"262.50\"
\n" ); document.write( "
\n" );
