Ivan read a total of 15 books over 5 months. After belonging to the book club for 8 months, how many books will Ivan have read in all? Solve using unit rates.
Because 15 books divide 5 months would be 3 books so each month is 3 books so 3 books times 3 more months would be 9 books and then you add 15 to 9 and you get 24.
