Answer: 50%
Step-by-step explanation:
Number of sixth-graders at Ethan's school = 76
Number of sixth-graders that picked the museum = 38
Number of sixth-graders that picked the factory = 76 - 38 = 38
Percentage that picked museum:
= Students that picked museum/Total students × 100
= 38/76 × 100
= 0.5 × 100
= 50%
50% picked the museum.
