Hi

using Proportions to determine drawings to scale:

1) 1"/(8') = x/40'  |cross multiply to solve

     8x = 40

      x = 5"

2) 6.5"/78' = 1/x 

     6.5x = 78

        x = 12'  Scale 1":12'

3) (27/8)"/x = 1"/4'

       x= (27/8)*4 = 27/2 = 13.5'



If I am understanding the question properly :)

111+333+777+999: replace five of the digits with 0's so that the sum equals 1,111

  333 + 777 = 1,110

 1,110 + 001 + 000 = 1,111
