Convert Improper Fraction to Mixed Number

You will need to convert an improper fraction to a mixed number. For example:

getMixedNum('18/11'); // Should return '1 7/11'
getMixedNum('13/5'); // Should return '2 3/5'
getMixedNum('75/10'); // Should return '7 5/10'

get_mixed_num('18/11') # Should return '1 7/11'
get_mixed_num('13/5') # Should return '2 3/5'
get_mixed_num('75/10') # Should return '7 5/10'

NOTE: All fractions will be greater than 0.
