Answer: Given that 23 sixth-graders picked the museum and 27 sixth-graders picked the factory, we can add these numbers together to find the total number of sixth-graders: 23 + 27 = 50.
Now, we can calculate the percentage by dividing the number of students who picked the museum (23) by the total number of sixth-graders (50), and then multiplying by 100.
23 / 50 = 0.46
0.46 x 100 = 46
So, 46% of the sixth-graders picked the museum.
