Explanation:

Solution:

a. when e = 11 and f = 7


\\ \: \: (e + 5)/(4f - 4)


\\ = (11 + 5)/(4 * 7 - 4)


\\ = (11 + 5)/(28 - 4)


\\ = (16)/(24)


\\ = { \cancel \frac{16}{{24}}}


\\ = (2)/(3)

b. when e = -1 and f = -4


\\ \: (e + 5)/(4f - 4)


\\ = \frac{{ - 1 + 5} }{4( - 4) - 4}


\\ = ( - 1 + 5)/( - 16 - 4)


\\ = (4)/( - 20)


\\ = { \cancel(4)/( - 20)}


\\ = ( - 1)/(5)
