i need help step by step

Answer:
225/900
Step-by-step explanation:
Because the previous year, 225 out of 900 received financial aid. That "out of" could be replaced by "/," and it still has the same meaning as 225 out of 900.
Answer:
1/4 (0.25) of the students received financial help
Step-by-step explanation:
Our starting fraction is 225/900. Looking at our fraction we see that our numerator and denominator end in a 5 or 0, meaning they are multiples of 5. So by dividing our numerator and denominator by 5 we get 45/180. That fraction (45/180) can be reduced to a smaller amount. As stated before, since both our numerator and denominator end in a 5 or 0; our numerator and denominator are multiples of 5. So by dividing our numerator and denominator fraction is reduced to 9/36. And since 36 is a multiple of 9 and 9 is a multiple of 9, by dividing both by 9 our final fraction is 1/4.
