For this case what we must do is multiply the fraction that Tara wants to finish reading by the total number of pages.
We know that:
1) Tara would like to finish 2/5 of her book by next friday.
2) the book has 203 pages
Therefore, the number of pages that Tara should read is:
[tex] N = \frac{2}{5}(203) [/tex]
Rewriting we have:
[tex] N = 81.2 [/tex]
Rounding to the next closest whole we have:
[tex] N = 82 [/tex]
Answer:
Tara needs to read at least 82 pages.
