Question

im trying to figure out the right answer

Answer 1

                                                             2/3     –       2/3 = 0 
                                                              ↑                 ↑  
1/2 + 2/3 + 3/4 - ((4/5) × (5/6)) = 1/2 + 2/3 + 3/4 - 20/30
LCD(2,4) = 4                                  ↓                ↓                  
                                                   2/4     +      3/4 = 5/4 = 1¼ = 1.25 

Answer 2

1/2 + 8/12 + 9/12 - 8/10*10/12 = 6/12 + 8/12 + 9/12 - 8/12 = 6/12 + 9/12 = 15/12 = 5/4
