Let x is the required amount to add in 1/3 to make 1 gallon
\n" ); document.write( "1/3+x=1
\n" ); document.write( "subtract 1/3 both sides of the equation
\n" ); document.write( "(1/3-1/3)+x=1-1/3
\n" ); document.write( "x=1-1/3
\n" ); document.write( "taking LCM on right side
\n" ); document.write( "x=(3-1)/3
\n" ); document.write( "x=2/3 gallon\r
\n" ); document.write( "\n" ); document.write( "So we need to add 2/3 gallon to 1/3 gallon to make 1 gallon.\r
\n" ); document.write( "\n" ); document.write( "Check\r
\n" ); document.write( "\n" ); document.write( "(1/3)+(2/3)=1
\n" ); document.write( "Taking LCM on left side\r
\n" ); document.write( "\n" ); document.write( "(1+2)/3=1
\n" ); document.write( "3/3=1
\n" ); document.write( "1=1\r
\n" ); document.write( "\n" ); document.write( "You have 1/3 gallon
\n" ); document.write( "
\n" );
