Answer:
The equation that shows how to find t, the total number of pages in the e-book is;
[tex]\frac{180}{t}=\frac{75}{100}[/tex]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.
[tex]\begin{gathered} 75\text{\% of t = 180 pages} \\ \frac{75}{100}\times t=180 \\ \frac{75}{100}=\frac{180}{t} \\ \frac{180}{t}=\frac{75}{100} \end{gathered}[/tex]Therefore, the equation that shows how to find t the total number of pages in the e-book is;
[tex]\frac{180}{t}=\frac{75}{100}[/tex]
