To find the percentage of boys in the school hall, we subtract the percentage of girls (9/25) from 100% since the sum of the percentages of boys and girls must equal 100%.
100% - 9/25 = 2500/2500 - 225/2500
= 2275/2500
So, approximately 91% of the pupils in the school hall are boys.
9/25 of the pupils in a school hall are girls. What percentage of the pupils in the school hall are boys?
