Hi, Previously Posted
Two numbers {{{x}}} and {{{y}}} are such that the ratio between them is 3:5.
  {{{ x/y = 3/5}}} or {{{x = (3/5)y}}}
If one is added to the one and 7 is added to the other, ratio becomes 1:2.
 {{{( (3/5)y + 1)/(y+7) = 1/highlight(2)}}}   |||Cross Multiplying to solve
    (y+7) = (6/5)y + 2
       5 = (1/5)y
       y = 25   and x = 15
