Answer 1

What do you mean by 1/2 12?

Answer 2

If your qustion means:

Jerome has 1 / 2 of the group’s video games at his house. Mario has 2 / 5
of the group’s video games at his house.

What fraction of the group’s video games is either at Jerome’s house or Mario’s house?

then

1 / 2 + 2 / 5 = 5 / 10 + 4 / 10 = 9 / 10 = 90 / 100 = 90%

Therefore, 9 / 10 = 90 % of the group's video games are either at Jerome or Mario's house.
