What is the quotient of the sum of the largest prime and the largest one digit within 50 divided by the smallest sum?

If the largest prime number within 50 is 47, then the sum of the largest prime number within 50 and the largest one digit is 47 + 9, and the smallest composite number is 4, then the quotient of the sum of the largest prime number within 50 and the largest one digit divided by the smallest composite number is: (47 + 9) △ 4 = 56 △ 4 = 14
