Question 1008894
,
ratio of age of father to child is 5:3 and mother to child is 5:2. what is the ratio of age of father to mother?
---------------------------------------------------------------

<pre>
Let me reformulate the problem in an equivalent form:


  The ratio of ages of father to child is {{{10/6}}}.
  The ratio of ages of mother to child is {{{15/6}}}.
  What is the ratio of ages of father to mother?


Now you easily find the answer: this ratio is {{{10/15}}} = {{{2/3}}}. 

(Although usually the father is older then the mother, but not nessesary).</pre>
