Answer:
The program is as follows:
num = float(input("Enter a decimal (float): "))
mult = int(input("Enter a positive whole (int): "))
small = (num // mult) * mult
big = small + mult
print(num,"rounded to the nearest multiple of ",mult,"is",end=" ")
print(big if num - small > big - num else small)
Explanation:
This gets input for num
num = float(input("Enter a decimal (float): "))
This gets input for mult
mult = int(input("Enter a positive whole (int): "))
This calculates the smaller multiple
small = (num // mult) * mult
This calculates the larger multiple
big = small + mult
This prints the output header
print(num,"rounded to the nearest multiple of ",mult,"is",end=" ")
This prints small if small is closer to num, else it prints big
print(big if num - small > big - num else small)
