Son = 1/5Mother
\n" ); document.write( "S+6 = 1/3(M+6) Substitute for Son
\n" ); document.write( "1/5M+6 = 1/3(M+6)
\n" ); document.write( "1/5M+6 = 1/3M+2
\n" ); document.write( "1/5M = 1/3M-4
\n" ); document.write( "1/5M-1/3M = -4
\n" ); document.write( "3/15M-5/15M = -4
\n" ); document.write( "-2/15M = -4 Divide both sides by 2/15 and remember -/- = +
\n" ); document.write( "M = -4/(-2/15) To divide by fraction invert and multiply
\n" ); document.write( "M = (4*15)/2
\n" ); document.write( "M = 30 The mother is 30 years old
\n" ); document.write( "S = 1/5M = 1/5*30 = (1*30)/5 = 6 The son is 6 years old
\n" ); document.write( "---------------------------
\n" ); document.write( "Check:In 6 years
\n" ); document.write( "30+6 = 36
\n" ); document.write( "6+6 = 12
\n" ); document.write( "1/3 of 36: 1/3*36 = (1*36)/3 = 12 Correct
