Give the step-by-step reasoning process and then the final answer. Zig wrote four times as many books as Flo. If Zig wrote 60 books, how many books did they write altogether?
If Zig wrote 60 books, four times as many books as Flo, Flo wrote 60 / 4 = 15 books. Together, they wrote 60 + 15 = 75 books.
The final answer: 75.
