If 8 out of 24 students scored below 75% marks in a test. Find the ratio of students scored below 75%marks to the students scored 75%and above marks.
Answers
Answer:
1 : 2
Step-by-step explanation:
Total number of students = 24 (Given)
Total number of students that scored below 75% = 8 (Given)
Find the number of student that scored 75% and above:
Total number of students that scored 75% and above = 24 - 8 = 16
Find the ratio of students scored below 75%marks to the students scored 75%and above:
Ratio = 8 : 16
(Simplify by dividing by 8)
Ratio = 1 : 2
Answer: The ratio is 1 : 2
Ratio is the comparison of two values by dividing them.
_________________________________________________
Number of students who scored below 75 % marks
Given 8 out of 24 students scored below 75%
The number of students is 8.............................(1)
___________________________________________________
Number of students who scored above 75% marks
Number of students who scored above 75% = total number of students - number of students who scored below 75%
==> Number of students = 24 - 8
==>Number of students = 16.................................(2)
____________________________________________________
Calculating the ratio
To calculate ratio of x to y we write it as x/ y
Here :
The required ratio is 8 : 16 [ See (1) and (2) ]
==> 8 / 16
==> 1 / 2
==> 1 : 2
___________________________________________________
The ratio of students who scored below 75% to the number of students who scored above 75% is 1 : 2
