Question

(4 13/18-3 7 /9)*(1/2-4/17)

Answer 1

(4 13/18-3 7 /9)*(1/2-4/17) = 19/68


                                                              13*1 - 7*2
(4 13/18-3 7 /9) = (4-3)+(13/18-7/9)= 1 + ------------------------ = 1+1/18= 1 1/18
                                                                     18
                        1*17 - 4*2                   17 - 8              9
(1/2-4/17) = ----------------------------- = ------------------- = -------------
                               34                         34               34


1 1/18 * 9/34 = 19/18 * 9/34 = 19/68
