Ian can type 1/3 of a page in 3/9 of a minute determine the pages he can type per minute

To determine how many pages Ian can type per minute, we first need to find out how long it takes him to type one full page.

Since Ian can type 1/3 of a page in 3/9 of a minute, we can simplify this to find out how long it takes him to type a full page:
(3/9) / (1/3) = (1/3) / (1/3) = 1

So it takes Ian 1 minute to type a full page.

Therefore, Ian can type 1 page per minute.
