the ratio of james's age and bob's age is 10:9.
\n" ); document.write( "let x = the multiplier
\n" ); document.write( "then
\n" ); document.write( "10x = j's age
\n" ); document.write( "and
\n" ); document.write( "9x = b's age
\n" ); document.write( " The ratio of sarah's age and bob's age is 29:27.
\n" ); document.write( "let y = the multiplier
\n" ); document.write( "then
\n" ); document.write( "29y = s's age
\n" ); document.write( "and
\n" ); document.write( "27y = b's age
\n" ); document.write( " how old is bob. (bob is between 40 and 70 years old
\n" ); document.write( "27y = 9x
\n" ); document.write( "3y = x
\n" ); document.write( "In order for Sarah's age to be reasonable, y has to equal 1 or 2
\n" ); document.write( "if y=1, x=3, Bob is 27, not between 40 and 70
\n" ); document.write( "if y=2, x=6, Bob is 54
\n" ); document.write( " \n" ); document.write( "
\n" );
