Answer:

61

Explanation:

If there are 6 coins on each page, then the number of pages for 600 coins is ...

(600 coins)/(6 coins/page) = 100 pages

__

If 39% are empty, then 100% -39% = 61% are filled.

The number of filled pages is ...

61% × 100 = 61/100 × 100 = 61 . . . . pages filled

_____

Comment about percent

You can think of the percent symbol (%) and "per 100" (/100) as being interchangeable. 61% = 61/100

("Cent" is used to signify one of 100 parts. A cent is 1/100 of a dollar, for example. In land area, a cent is 1/100 of an acre. Then, "percent" can be thought of as "per cent" or "per 100 parts".)
