The fraction of computer and video game players that are 18 years old or more is 3/4.

Step-by-step explanation:

Under 18: 25% or 1/4

25% → 25/100 → 5/20 (divided by 5) → 1/4 (divided by 5)

18 years old or more: 45% (18 to 49) + 30% (50 or more) → 75% or 3/4

75% → 75/100 → 15/20 (divided by 5) → 3/4 (divided by 5)
