You know that 14/32 are boys. Divide this out and you get 0.4375, move the decimal two places to the right and you get 14/32 = 43.75%. The percentage of boys plus girls must equal 100%, so knowing that is the percentage of boys, 100% minus 43.75% must equal the percentage of girls. 100% - 43.75% = 56.25% so 56.25% is the percentage of girls in the class.
