What should be added to (-7/20) to get (-2/5)?
\n" ); document.write( "--------------
\n" ); document.write( "(-7/20) + what = (-2/5)
\n" ); document.write( "Subtract (-7/20) from both sides
\n" ); document.write( "what = (-2/5) - (-7/20)
\n" ); document.write( "Get a common denominator
\n" ); document.write( "what = (-8/20) - (-7/20)
\n" ); document.write( "- times - = +
\n" ); document.write( "what = (-8/20) + 7/20
\n" ); document.write( "Combine
\n" ); document.write( "what = -1/20
\n" ); document.write( " \n" ); document.write( "
