Thank you for the opportunity to help you with your question!

(-5/8 - 4/5) - (-9/8 - 5)

first do the subtractions in brackets

=(-5*5 - 4*8 / 5*8) - (-9- 5*8/8)

=(-25 - 32 / 40) - (-9- 40 / 8)

= (- 57 / 40) - (-49 / 8)

= - 57 / 40 + 49 / 8

 = - 57  + 49 *5 / 40

 = - 57  + 245 / 40

= 188/40

 = 47 /10.............................ANSWER

 =  4.7    ..................................ANSWER
