Question

Mr elliot can grade 50 papers in 20 minutes how many papers can he grade in one minutes

Answer 1

$50 \div 20$
Since you want to find out how many papers Mr. Elliot grades per minute, and he grades 50 every 20 minutes, divide 20 by 20, and you get 1 minute, and now divide 50 by 20, and you get 2.5 papers per minute. Mr. Elliot grades 2.5 papers per minute.
