10 * .6 = 6

So 6 more should grow

Step-by-step explanation:

16/2=8

that would be the answer for how many books he got for free because if there is a box of 16 books and for every2 books you get one free then you would divide 16 and 2 and get 8 then

16+8=24

add the number of books he got for free with the original 16 books he already had and get 24 total books.
