Henry and saniel volunteer at the daycare sensor henley works three hours for every two hours samuel words if the two boys together work 20 hours one month how many hours does henry work

Henry worked 12 hours and samuel worked 8 hours. if the ratio of their hours is 3: 2, henry's hours have to be slightly over 1/2 the total hours. 20/2 equals 10, so let's try 12 for the "slightly over." if henry worked 12 hours, then samuel will have worked 8 hours. 12/4 is 3 and 8/4 is 2, so the ratio is 3: 2. 12 plus 8 equals 20, so the total hours is also correct.
