# If Rational is an improper fraction, removes the integer part to convert to a mixed fraction.
#
# @example Mixed fraction
# Rational(4,3).to_simplified_s #=> "1 1/3"
# @return [String] If less than 1, fraction. If greater than 1, a mixed fraction.

# Converts Rational to Array

# If Rational is an improper fraction, removes the integer part to convert to a mixed fraction.

# @example Mixed fraction
# Rational(4,3).to_simplified_a #=> [1, Rational(1,3)]
# @return [Array] If less than 1, fraction. If greater than 1, a mixed fraction.
