Question

if 9 out of 24 scored below 75% marks  in a test.find the ratio of students scored below 75% marks to the student scored 75%and above marks

Answer 1

no. of students scored below 75% marks = 9
no. of students scored 75% and above = 24-9 =15

Ratio of students scored below 75% to the students scored 75%and above = $\frac{9}{15} = \frac{3}{5}$

Answer 2

Answer:

Ratio of students below and above 75% is 3:5

Step-by-step explanation:

Total number of student in a class=24 students

Number of students achieved below 75%marks =9 students

Number of students achieved above 75% marks= (total no.of.students) - (no.of students scored below 75% marks)

       =24-9  

       =15 students

Number of students achieved above 75% is 15 students

Thus the ratio of students scored below 75% to the ratio of students scored above 75% marks is 9:15 or 3:5

Ratio of students below and above 75% is 3:5
