answer

Answer 2

Answer:

D 3:4 is the answer

Step-by-step explanation:

let passed students = 2x

failed students = 3x

5x = total number of students

5x = 225

x= 45 so 2:3 can be the ratio

let passed students = 7x

failed students = 8x

15x = 225

x = 15 so 7:8 can be the ratio

let passed students = 5x

failed students = 4x

9x = 225

x = 25 so 5:4 can be the ratio

let passed students = 3x

failed students = 4x

7x = 225

x = 32. students cannot be divided into points eg 1/2 student

so 3:4 cannot be the ratio of this question
