Question

Verify that:- -20+ [3/-5+(-7)/(-10)] = [-20+ 3/-5]+ -7/-10].

Answer 1

After separately simplifying both sides of the given equality, it is verified that -20 + [3/-5 + (-7)/(-10)] is equal to [-20 + 3/-5] + -7/-10, both simplifying to -19.9.

Step-by-step explanation:

To verify the equality -20 + [3/-5 + (-7)/(-10)] = [-20 + 3/-5] + -7/-10, we need to simplify both sides separately and check if they result in the same value.

• Start with the left side:
  
• Now, simplify the right side:
  

Each side simplifies to -19.9. Therefore, the given expression is verified and holds true, demonstrating the associative property of addition.
