Question 406257

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
