Python Coding Challenge - Question with Answer (ID 210826)

Explanation:

1. Import Fraction

from fractions import Fraction

The fractions module provides the Fraction class for working with exact rational numbers.

For example:

Fraction(3, 4)

represents exactly:

3/4

Unlike floating-point numbers, Fraction keeps the result exact.

2. Create and Multiply Fractions

x = Fraction(3, 4) * Fraction(8, 9)

Here, two fractions are created:

Fraction(3, 4) → 3/4

Fraction(8, 9) → 8/9

Python multiplies them:

3/4 × 8/9

3. Simplify the Result

Multiply the numerators:

3 × 8 = 24

Multiply the denominators:

4 × 9 = 36

So:

24/36

Python automatically simplifies this fraction:

24/36 = 2/3

Therefore:

x

contains:

2/3

4. print(x)

print(x)

The print() function displays the value stored in x.

✅ Final Output

2/3
