Assuming that the first column of numbers is boys and the second column is girls, you would do the number of boys who prefer watching movies at the theater divided by the total number of boys. 44/(44+17)=72% of boys prefer to watch movies in a theater. You would do the same thing for girls. You take the number of girls who prefer to watch movies at home divided by the total number of girls. 23/(23+38)=38%
