if 1/8 of a pencil is black 1/2 of the remaining is white and the remaining 7/2 is blue find the total length of the pencil?

• The real problem speaks of "7/2 cm" is blue, here that cm part is missing.
  
  Solution::
  
  (1/8)p + (1/2)p + (7/2)= p
  
  on solving the above for p we get 9.333
  
  Now checking for the answer:
  
  9.333/8=1.166 cm
  9.333/2=4.665 cm
  
  now 1.166+4.665+(7/2) = 9.33cm
