Question

Hypatia has read 13 chapters of a 22 chapter book what percent has she read

Answer 1

She has read 59% of the book so far, you simply divide and get a decimal which you round to

Answer 2

59.09%

Explanation:

We can calculate it with a direct rule of 3. If 22 chapters are the 100% of the book, what percent is 13 chapters?

`\text{22 chapters} -\!\!\!-\!\!\!- 100\%\\ \\\text{13 chapters} -\!\!\!-\!\!\!- x\%`

We use the formula of the direct rule of 3:

`x = \frac {13* 100}{22} \\ \\ x = \frac {1300}{22}`

x = 59.09

She has read the 59.09% of the book.
