a class has 60 students. Given that 85% passed a science test. Find the number of students who failed and then convert o %

Given:

Total students = 60

Student passed = 85%

To find:

The number of students who failed and  then convert it in %.

Solution:

We have,

Number of passed student = 85% of Total students

                                            =

                                            =

So, number of passes students is 51.

Number of students who failed = Total students - Passes students

                                                    =

                                                    =

So, number of students who failed is 9.

Therefore, 15% students fail in the test.
