how to solve it?
\n" ); document.write( "if the numerator of a fraction is increased by 20% &
\n" ); document.write( "its denominator by 25% then the fraction so obtained is 3/5.
\n" ); document.write( " what is the original fraction?
\n" ); document.write( ":
\n" ); document.write( "The multiplier for a 20% increase is 1.20, for 25% increase is 1.25
\n" ); document.write( ":
\n" ); document.write( "Let n = the original numerator
\n" ); document.write( "Let d = the denominator
\n" ); document.write( ":
\n" ); document.write( "1.2n = 3
\n" ); document.write( "n = 3/1.2
\n" ); document.write( "n = 2.5
\n" ); document.write( "and
\n" ); document.write( "1.25d = 5
\n" ); document.write( "d = 5/1.25
\n" ); document.write( "d = 4
\n" ); document.write( ";
\n" ); document.write( "\"2.5%2F4\" but the numerator has to be an integer, mult by 2/2
\n" ); document.write( "\"2.5%2F4\"*\"2%2F2\" = \"5%2F8\" is the original fraction\r
