6.5.5 Divisibility Part 2 CodeHS Answers

The most common answer is:

numerator = int(input(“Enter a numerator: “))
denominator = int(input(“Enter denominator: “))
If denominator is 0, this will result in a division-
by-zero error! Add in code to solve this issue:
try:
if numerator / denominator * denominator == numerator:
print “Divides evenly!”
except ZeroDivisionError:
print “Doesn’t divide evenly.”

To correctly handle division by zero and check for divisibility, we can modify your code to use a try-except block properly and ensure the usage of standard ASCII quotation marks.

Additionally, the logic for checking divisibility can be simplified by using the modulo operator %, which directly checks if the remainder of the division is zero.

Here’s the revised version of the code:

numerator = int(input("Enter a numerator: "))
denominator = int(input("Enter a denominator: "))

# Checking for division by zero and divisibility
try:
    # Correct way to check for divisibility
    if numerator % denominator == 0:
        print("Divides evenly!")
    else:
        print("Doesn't divide evenly.")
except ZeroDivisionError:
    print("Cannot divide by zero.")

This program will:

• Prompt the user to enter a numerator and a denominator.
• Use a try-except block to catch and handle division by zero errors.
• Check if the numerator divides evenly by the denominator using the modulo operator %.
• Print “Divides evenly!” if there’s no remainder.
• If the denominator is zero, it will catch the ZeroDivisionError and print “Cannot divide by zero.”
