pls answer step by step pls pls pls ​

Answer 1

Answer:

 19/14      or can be written as 1 (5/14)

Step-by-step explanation:

= (1/7+8/5)+(-3/14+6/-35)

By taking LCM of 7 and 5 = 35 in first bracket and LCM of 14 and 35 = 70 in second bracket.

= (1*5/7*5  +  8*7/5*7)   +     (-3*5/14*5  + 6*2/-35*2)

= (5/35     +     56/35)    +    (-15/70       -         12/70)

=  (5+56)/35                   +       (-15-12)/70

=     61/35                      +       (-27)/70

Now taking LCM of 35 and 70 = 70

=       61*2 / 35*2            +       (-27)/70

=           122/70            -      27/70

=           95/70

Dividing by 5

=            19/14      or 1 (5/14)
