Since we all know 1/E[x] and E[1/x] are not quite the same. I was wondering how does one decide where to use which expression ?

For example: I have an inequality :

A < B*E[C]

which i can manipulate to 1/A > 1/B*E[c]. But lets assume i didn't know the first expression how can i decide which expression is correct :

1/A > 1/B*E[C]


1/A > (1/B)*E[1/C]
