Answer :
30 seconds because if you multiply the 1/6 to get common denominator of 12, you will get 2/12, then multiply both fractions by 6 to get 12/12 which is a full page and 6/12 which is 30 seconds
to find out how long it take for him to write a full page, multiply 1/12 by 6. which is 6/12, if you simplify it, it would be 1/2. that means it take him 1/2 of a minute to write a full page, it other words, it take him 30 seconds to write a full page.
