Can someone check and tell me if these are correct or not.
subtract 8853=
Subtract 7/9  (13/18)=11/18
multiply (3)(7)(9)=189
find the reciprocal of (1/7)(14/3)(9)

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)
