The ratio of boys to girls in a classroom is 3:5. If there are 4 more girls than boys, how many students are in the classroom? Give me reasons, before answering the question
Since the ratio of boys to girls is 3:5, then the class is divided into 3 + 5 = 8 parts. The girls have 5 - 3 = 2 parts more than the boys. Since 2 parts are equal to 4, then 1 part is equal to 4 / 2 = 2 students. Hence, there are 8 parts x 2 = 16 students. So the final answer is 16.
