Answer 1

Question:

Verify $-\frac{2}{5} + (\frac{3}{5} +\frac{1}{2}) = (-\frac{2}{5} + \frac{3}{5}) +\frac{1}{2}$

Step-by-step explanation:

The above equation verifies associative property of addition.

Now, we will verify above equation.

$-\frac{2}{5} + (\frac{3}{5} +\frac{1}{2}) = (-\frac{2}{5} + \frac{3}{5}) +\frac{1}{2}\\\\-\frac{2}{5} + (\frac{6}{10} +\frac{5}{10}) = (\frac{1}{5} ) +\frac{1}{2}\\\\-\frac{2}{5} + (\frac{11}{10}) = (\frac{2}{10} ) +\frac{5}{10}\\\\-\frac{4}{10} + (\frac{11}{10}) = (\frac{7}{10} )\\\\\frac{7}{10} = (\frac{7}{10} )\\\\ LHS = RHS$

Hence, verified.
