You are given the label so you don't really need to calculate anything except % daily calories. Calculate that by calories divided by total daily 2000 calories times 100. Copy the percentages for the other stuff directly from the label. 
 
For the 670 calorie whooper 
100 * 670/2000 = 33.5% of you daily calories. 
The rest of the percentages are given on the label for a 2000 calorie diet, 
For the 560 calorie bigmac 
100 * 560/2000 = 28%
