Question

Write the percent as a rate per 100 170/t= ?/100

Answer 1

The equation that shows how to find t, the total number of pages in the e-book is;

`(180)/(t)=(75)/(100)`

Step-by-step explanation:

Given that after reading 180 pages, he has completed 75% of the book.

It implies that 75% of the total number of pages is 180 pages.

`\begin{gathered} 75\text{\% of t = 180 pages} \\ (75)/(100)* t=180 \\ (75)/(100)=(180)/(t) \\ (180)/(t)=(75)/(100) \end{gathered}`

Therefore, the equation that shows how to find t the total number of pages in the e-book is;

`(180)/(t)=(75)/(100)`
