You can put this solution on YOUR website!
not sure how old you are or your level of maths (\"math\" if you're American), but just put the numbers in the equation, where you see the relevant letter:\r
\n" ); document.write( "\n" ); document.write( "% = \"+%28%28-98.42%29+%2B+%284.15%2Aw%29+-+%280.082%2Ab%29%29%2F%28b%29\" gives\r
\n" ); document.write( "\n" ); document.write( "% = \"%28%28-98.42%29+%2B+%284.15%2A32%29+-+%280.082%2A156%29%29%2F156\" assuming that the numbers are in the correct units for this equation. Now just work it out...\r
\n" ); document.write( "\n" ); document.write( "% = \"%28-98.42+%2B+132.8+-+12.792%29%2F156\"\r
\n" ); document.write( "\n" ); document.write( "% = \"21.588%2F156\"
\n" ); document.write( "% = 0.138\r
