Q: Im 27(male) How do i build up on my chest and sametime to loss fat at my abs?

A: If you're a complete beginner you'll be able to make some progress on both for a few months by taking up heavy whole-body weight training and a moderate fat-burning diet. After those few months however you will probably want to pick either building muscle or losing fat as your goal and structure your diet accordingly (your training need not change) since by trying to do both at the same time you'll just end up running in place. This is because building muscle in general requires slight overeating to very slowly gain weight while burning fat in general requires slight undereating to slowly lose weight. The first few months for a beginner are a bonus period when you'll be able to do both at the same time while losing weight. But after that you'd be well advised to focus on one or the other.
