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

                                            = \dfrac{85}{100}\times 60

                                            = 51

So, number of passes students is 51.

Number of students who failed = Total students - Passes students

                                                    = 60-51

                                                    = 9

So, number of students who failed is 9.

\text{Fail}\%=\dfrac{\text{Failed students}}{\text{Total students}}\times 100

\text{Fail}\%=\dfrac{9}{60}\times 100

\text{Fail}\%=15

Therefore, 15% students fail in the test.

Sienna, Rhys, and Micah are all reading the same book for school. Sienna has read 40% as far as Rhys has, and Rhys has read 40%
ruslelena [56]

Based on the fact that Sienna has read 60 pages, we can infer that Micha has read 375 pages of the book.

Sienna has read 40% of what Rhys has read and that corresponds to 60 pages. The number of pages read by Rhys is therefore:

<em>= Number of pages / Percentage read </em>

= 60 / 40%

= 150 pages

The 150 pages read by Rhys is 40% of what Micah has read. Micah has therefore read:

= 150 / 40%

= 375 pages

In conclusion, Micah has read 375 pages.
