    STEP BY STEP EXPLANATION:

    sum of -4/5 and 1/4 = (-4/5) + (1/4)………….(make the denominator same)

                                    = -11/20

    subtract their sum ( -11/20 ) from 1 = 1 – ( -11/20 )

                                                            = 1 + 11/20…………..( when you open the  

                                                                                           bracket the – sign                            

                                                                                            changes to + sign)

                                    ∴ 1 + 11/20

                                     = 20/20 + 11/20…………(make the denominator same)

                                     =31/20
