The answer is 34.4 percent because you divide 1000 by 10 and get 100. Then you divide 344 by 10 to get 34.4% so this is the answer because it is out of 100 now.
344 of 1000 is 344/1000 which would be .344 which translates to 34.4% (to get this you move the decimal to the right 2 places because .344 ( read three hundred and forty-four thousands) is a thousandth and a percent is of 100)
