45. Fraction from Decimal Conversion

Write a Python program to create fraction instances of decimal numbers.

Sample Solution:

Python Code:

import decimal
import fractions
values = [
    decimal.Decimal('0.2'),
    decimal.Decimal('0.7'),
    decimal.Decimal('2.5'),
    decimal.Decimal('3.0'),
]

for d in values:
    print('{} = {}'.format(d, fractions.Fraction(d)))
	

Sample Output:

0.2 = 1/5                                                                                                     
                                                                                                              
0.7 = 7/10                                                                                                    
                                                                                                              
2.5 = 5/2                                                                                                     
                                                                                                              
3.0 = 3
