# How to iteratingiterate through a list of rules?

Let's consider I have a list of rules:

{Aa ->1> 1/2, Av ->2> 2/5, Bx ->3> 3/7, Ce ->4> 4/9, ...}


I want to find all keys that contain "a"the letter "A" and change their values to expressions. This means to have as a result:

***Some code here...***
{Aa ->ToExpression[1> ToExpression[1/2], Av ->ToExpression[2> ToExpression[2/5], Bx->3/7, Ce->4/9, ...}


Thanks for any help!
