Timothy saw 9/10 of the exhibits in the art museum. Ray saw 3/5 of the exhibits in the art museum. Alice saw 1/6 of the exhibits in the art museum. Who saw about 1/2 of the exhibits in the art museum?

The answer is ray

explanation:

you have to convert the fractions to the same denominator, which in the case is 30. so timothy would be 27/30, ray would be 18/30, and alice would be 5/30. since it asks for 1/2 you do 30 divided by 2 to find that 15 is half of 30. and since ray is closer to 15 he saw at least 1/2 of the exhibits.
