The answer can be B and C actually. The easiest way I was taught to change a mixed number into a improper fraction is multiply the big number by the denominator and then add the numerator and that'll be the numerator to the improper fraction.
no the answer is just b because a mixed number is defined as an integer and a proper fraction. c may be equivalent to 23/3 but 5/3 is an improper fraction not a proper faction, so it’s not a mixed number, leaving you with the correct answer, b.
