Can someone check and tell me if these are correct or not.

subtract -88-53=

Subtract 7/9 - (-13/18)=-11/18

multiply (3)(7)(-9)=-189

find the reciprocal of (-1/7)(14/3)(9)

  • math -

    You have not provided an answer to the first one.

    The second one is wrong. Tou are adding two positive fractions and so cannot get a negative number. Concert 7/9 to 14/18 and add the fractions. Then reduce to lowest terms. The answer might be an integer.

    The third answer is correct.

    The reciprocal will be (-7)(3/14)(1/9)
    (Multiply the reciprocals of each factor)
