Since 2/7 of class learn german, 1/2 learn spanish, and the rest learn italian, we can add the 2/7 and 1/2 and subtract them from 1 to get the percentage of students who learn italian. From here, you will get 3/14. Now, divide this to 6, the number of students who want to learn italian, to get the number of students. The answer is 28.
