To find the reciprocal of a fraction you'd switch the numerator with the denominator but since this is a mixed number, multiply the whole number by the denominator then add the numerator and you get a improper fraction and if you get that to find the reciprocal of it, switch the numerator with the denominator(ex. 3 4/5= 3X5=15, 15+4=19, 19/5, reciprocal: 5/19)
