The ratio of the youngest to the oldest is 1:5, part of the given combined ratio.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Oldest child, z,
\n" ); document.write( "z=12+x, using x for youngest child.
\n" ); document.write( "Think about their ratio again.
\n" ); document.write( "\"1%2F5=x%2F%2812%2Bx%29\"
\n" ); document.write( "Solve for x, the age for the youngest child.
\n" ); document.write( "\"1=5x%2F%28x%2B12%29\"
\n" ); document.write( "\"x%2B12=5x\"
\n" ); document.write( "\"12=4x\"
\n" ); document.write( "\"highlight%28x=3%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Look again at the full ratio expression. The second child is \"x%2A3=3%2A3=highlight%289%29\" years of age.
