We have $\"1%2F4\"$ + $\"1%2F5\"$ = $\"1%2Fx\"$
\n" ); document.write( "First, let's find the common denominator of $\"1%2F4\"$ and $\"1%2F5\"$ and add them.\r
\n" ); document.write( "\n" ); document.write( "We know both 4 and 5 will multiply into 20, so let's 20 as our common denominator.\r
\n" ); document.write( "\n" ); document.write( " $\"1%2F4\"$ + $\"1%2F5\"$ = $\"5%2F20\"$ + $\"4%2F20\"$ = $\"9%2F20\"$ \r
\n" ); document.write( "\n" ); document.write( "So now we have,
\n" ); document.write( " $\"9%2F20\"$ = $\"1%2Fx\"$ First let's multiply both sides by x
\n" ); document.write( " $\"9%2F20\"$ x = $\"1%2Fx\"$ *x
\n" ); document.write( " $\"9%2F20\"$ x = 1 (Now divide both sides by $\"9%2F20\"$ )
\n" ); document.write( " $\"%289%2F20%29%2F%289%2F20%29\"$ x = $\"1%2F%289%2F20%29\"$
\n" ); document.write( "x = $\"1%2F%289%2F20%29\"$ = $\"20%2F9\"$ \r
