  1. The multiplicative inverse of the number is that number which when multiplied gives you 1

    so (?)(-9) = 1

    must be -1/9

  3. To form the multiplicative inverse of a fraction , simply take its reciprocal,

    e.g. for 4/7 , its x-inverse is 7/4
    (4/7)(7/4) = 28/28 = 1

    To form the multiplicative inverse of a mixed fraction, change the mixed fraction to an improper fraction and proceed as above

    e.g. 4 3/5
    = 23/5
    so the x-inverse is 5/23
