Question

verify - 20 +( 3 / - 5 +- 7 / - 10)= (-20+3/-5)+-7/-10
​

Answer 1

The expression is true.

Step-by-step explanation:

The expression is:

$- 20 +( \frac{3}{- 5} +\frac{- 7}{- 10})= (-20+\frac{3}{-5})+\frac{-7}{-10}$

Compute the value of the right hand side of the equation:

$(-20+\frac{3}{-5})+\frac{-7}{-10}=-20-\frac{3}{5}+\frac{7}{10}=\frac{-200-6+7}{10}=\frac{199}{100}$

Compute the value of the left hand side of the equation:

$- 20 +( \frac{3}{- 5} +\frac{- 7}{- 10})=-20-\frac{3}{5}+\frac{7}{10}=\frac{-200-6+7}{100}=\frac{199}{100}$

The LHS = RHS.

Thus, the expression is true.
