Extracted text: PROBLEM 5: Using if-else /Nested if-else if structure, write a complete program a.) that will determine which among the 3 numbers entered from the keyboard is the largest and which is the smallest. b.) that will also determine and print the final grade equivalent of the average grade entered from the keyboard. The equivalent grade will be based on the Table of Transmutation of Grades shown below: Average Final Grade Below 50 5.0 Sample Input/Output: 50 to 60 3.0 Enter 3 numbers: 5 8 3 Largest = 8 Enter the Average Grade: 75 61 to 80 2.0 Smallest = 3 81 to 90 1.5 91 to 100 1.0 Final Grade = 2.0 (Note : Use only one program file )
