Respuesta :
6 months.
Because, weston can only read a total of 12 books in 3 months. So we just add it up ...
12+12= 24
3months + 3months = 6 months
Writing and solving an equation of ratios would be the best way to go here.
24 books x
--------------- = ------------
12 books 3 mo
Then 12x=72, and x = 6. It will take Weston 6 months to read 24 books.
