Answer 3

Sure, let's solve the expression step by step:

1. (-5.3/7 + 5.1/14):

   • First, find a common denominator, which is 14 in this case.
   • Convert both fractions to have a denominator of 14:
     • (-5.3/7) * (2/2) = -10.6/14
     • (5.1/14) * (1/1) = 5.1/14
   • Add the two fractions: -10.6/14 + 5.1/14 = -5.5/14

2. (5/7 + (-5/7)):

   • Simply add the fractions: 5/7 + (-5/7) = 0/7 = 0

3. -5.5/14 + 0:

   • Adding -5.5/14 and 0 gives you -5.5/14.

So, the final result of the expression is -5.5/14.
