How to lose belly fat (and all the fat around it)?

So, I am 17 and I used to lift weights in my sophomore year of high school (I am about to be a senior in high school). I added on a lot of mass to my arms, pecs, legs, etc. Meanwhile, I was developing a little bit of a belly but thought "hey, I can take care of it later it won't get too bad". Now, I actually have a full blown belly. I mean, when I wear a shirt you can't really tell of course, but if I keep going at this rate it will be bad. Right now its mainly all fat. I'd say around 25%-30% body fat right now, and I am wondering how should I go about losing all this fat around my belly and flattening my stomach and in general losing all the fat on my torso. I know a lot of toning exercises will help (lots of reps), but I am wondering what is the best and fastest method to lose all this body fat and cut my body fat percentage down to like 12%-6% (after all, school starts in September, and I want to come back to school looking damn good).

the only way to lose fat is cardio which is the only fat burning exercise - running, jogging, swimming, cycling, rope jumping, hiking etc. - do it 4-6 times a week for average of 45min.
toning exercises only tone - they dont burn any fat.
and eat healthy, fresh, unprocessed foods, small meals every 2-3 hours that way your body gets enough calories when it needs them and doesnt have any extra left to store in fat reserves (which happens when you eat 3 big meals a day)
