A special school for deaf and blind students has a deaf student population three times the size of blind student population. If the number of deaf students is 180, how many students are there altogether? Give me reasons, before answering the question

Call the number of blind students b. There are 180 deaf students, which is three times the number of blind students, so 3b = 180. Multiplying both sides of the equation by 1 / 3 gives b = (1 / 3) * 180 = 60. The total number of students is 180 + 60 = 240. So the final answer is 240.
