Please help me understand how they got these percentages

Hi! First time posting, let me preface by saying I'm not the best at math. I play a mobile game where we keep track of certain things, I want to understand how they have gotten these percentages. I'm not quite sure how to get them.

I tried doing these on my own, but am always slightly off or majorly off.

7365052 : 609560941 = 14730104 : 1219121882 = 1.2%?

then i tried another: 4427200 : 62610116 = 1106800 : 15652529 but the percentage above on the table is 7.16% not 1.5%.. I'm very lost.
