What is the least number which when added to both the terms of the fraction 7/9 will give a ratio equal to 19/23?

• 2.5
  
  If x is the number, then
  (7+x)/(9+x) = 19/23
  solving it, we get
  x=2.5
  
  check 9.5/11.5 = 19/23

• the answer is 5/2
  let y be the least number
  (7+y)/(9+y)=19/23
  161+23y=171+19y
  4y=10
  y=5/2
