Check out the pdf attached to see how to do this problem. It will give you a way of solving all ratio problems. But the final answer 176-124 = 52 there are 52 more girls than boys.
80 is 40% of 200 because 40%of 100 is 40. Common sense is just to double both values, also 200 x .40 (40%as a decimal) gives you the result of 80.
