Minority Interest and EV

Hi, hoping someone could provide insight. I recognize that you add minority interest as part of the EV calculation as a way of making a multiple "apples-to-apples." I had a few additional questions. Thank you.

1) For a company that owns 50+%, but not 100%, I know that the balance sheet and income statement (and cfs?) act as if 100% is owned. But if the income statement has an adjustment saying how much is attributable to the the minority owner, why don't you just take that amount out and then just do EV/EBITDA? I was thinking that because the balance sheets are consolidated then EV would still be wrong since the cash and debt on the balance sheet would be the sum of both companies. Wanted to know if this reasoning is correct? If so, then is it right to just add in the minority interest with all the other usual components to get EV and then divide EBITDA (that add rather than subtracts income owed to minority interests). Basically my question is about what net income do you use for the EV calc if you adjust for minority interest? Do you subtract the income attributable to minority interests or do you subtract and why?

2) For the equity value of the minority interest, wouldn't you rather you market cap than book value? I recognize that limited info is often a limitation, but what would be done here in a perfect world.
