\n" ); document.write( ":
\n" ); document.write( "Let x = the other number
\n" ); document.write( "\"4%2F5\"x = 30
\n" ); document.write( "multiply both sides by 5
\n" ); document.write( "4x = 150
\n" ); document.write( "x = 150/4
\n" ); document.write( "x = 37\"1%2F2\"
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this using decimal values, x = 37.5 and 4/5 = .8
\n" ); document.write( ".8 * 37.5 = 30
\n" ); document.write( "
