46. Arithmetic on Fractions

Write a Python program to add, subtract, multiply and divide two fractions.

Sample Solution:

Python Code:

import fractions

f1 = fractions.Fraction(2, 3)
f2 = fractions.Fraction(3, 7)

print('{} + {} = {}'.format(f1, f2, f1 + f2))
print('{} - {} = {}'.format(f1, f2, f1 - f2))
print('{} * {} = {}'.format(f1, f2, f1 * f2))
print('{} / {} = {}'.format(f1, f2, f1 / f2))

Sample Output:

2/3 + 3/7 = 23/21                                                                                             
2/3 - 3/7 = 5/21                                                                                              
2/3 * 3/7 = 2/7                                                                                               
2/3 / 3/7 = 14/9
