#9# days

Explanation:

If she has read 110 pages of 290 pages
she has #290 " pages" - 110 " pages" =180" pages" left to read.

If she reads 20 pages per day
it will take her #(180" pages")/(20 " pages"/" day") = 9 " days"# to finish the book.

See a solution process below:

Explanation:

First, we need to determine how many pages of the book Tehira has to read.

To find this we can subtract the number of pages Tahira has read from the total number of pages in the book giving:

#290 - 110 = 180# pages left to read.

If she reads 20 pages each day or per day we can write:

#180/20 = 9# days of reading left.
