Alright, so this is a simple matter. you need to look for the common factor in them. 2 and 5 are 10. so 2 x 5 = 10 and 1 x 5 = 5. 2 x 2 = 4 and 5 x 2 = 10.
Now that we have that. 5/10 of the video games are at Jerome's house.
4/10 of the games are at Mario's house EHM EHM SUPER MARIO.
Hope this helps.
