Answer:3 9/11
Step-by-step explanation:
First we need to convert both numbers to mixed numerals. Just search it up on the internet if ur dont know how to do that. Then once you have them both, 21/2 and 11/4, you divide the fractions (multiply by reciprocal) and you get 42/11. reconvert back to mixed numeral and u get 3 9/11
