There are 380 students surveyed. Also, 57 of the students stated that their favourite colour was red. Hence, we can construct a fraction here, and it would be 57/380. Now, we divide the fraction - like 57 divided by 380 to get a decimal to convert to a percent. As a result, we get 0.15, then we multiply 0.15 by 100 to get 15% as our final answer.
