oh come on i need help !!!!!!!!!!!!!!

plz someone idc how it is!!!

say there were100 games

Jerome has 50
Mario has 2/5 * 100 = 40
together they have 90
90/100 = 9/10

To find the fraction of the group's video games at either Jerome's or Mario's house, we need to add the fractions representing the games at each house.

Step 1: Find a common denominator for 2 and 5. The least common multiple (LCM) of 2 and 5 is 10.

Step 2: Convert the fractions to have the same denominator.

1/2 = (1/2) * (5/5) = 5/10
2/5 = (2/5) * (2/2) = 4/10

Now both fractions have the same denominator of 10.

Step 3: Add the fractions:

5/10 + 4/10 = 9/10

Therefore, the fraction of the group's video games at either Jerome's or Mario's house is 9/10.
