1) Find two consecutive even numbers such that the difference of one-half of the larger and two-fifths of the smaller is equal to five.
\n" ); document.write( "Two consecutive even numbers; x, (x+2), (we can us decimals here 2/5 = .4)
\n" ); document.write( ".5(x+2) - .4x = 5
\n" ); document.write( ".5x + 1 - .4x = 5
\n" ); document.write( ".5x - .4x = 5 + 1
\n" ); document.write( ".1x = 4
\n" ); document.write( "x = \"4%2F.1\"
\n" ); document.write( "x = 40
\n" ); document.write( "40,42 are the numbers
\n" ); document.write( ":
\n" ); document.write( "Check
\n" ); document.write( ".5(42) - .4(40) =
\n" ); document.write( "21 - 16 = 5
\n" ); document.write( ":
\n" ); document.write( ";
\n" ); document.write( "2)Find three consecutive numbers such that the sum of one-third of the first and one-seventh of the second is two less that one-half of the third
\n" ); document.write( "x, (x+1), (x+2)
\n" ); document.write( "\"1%2F3\"x + \"1%2F7\"(x+1) = \"1%2F2\"(x+2) - 2
\n" ); document.write( "Get rid of those annoying fractions, multiply by 42, results:
\n" ); document.write( "14x + 6(x+1) = 21(x+2) - 42(2)
\n" ); document.write( ":
\n" ); document.write( "14x + 6x + 6 = 21x + 42 - 84
\n" ); document.write( ":
\n" ); document.write( "20x + 6 = 21x - 42
\n" ); document.write( ":
\n" ); document.write( "6 + 42 = 21x - 20x
\n" ); document.write( ":
\n" ); document.write( "48 = x
\n" ); document.write( ":
\n" ); document.write( "48, 49, 50 are the three numbers
\n" ); document.write( ":
\n" ); document.write( "Check solution
\n" ); document.write( "\"1%2F3\"(48) + \"1%2F7\"(49) = \"1%2F2\"(50) - 2
\n" ); document.write( "16 + 7 = 25 - 2
