Answer 2

Associative Property Over Addition.

Step-by-step explanation:

Verification -

[Property Used= Associative property over addition- possible]

$\frac{2}{3} + [ \frac{2}{7} + \frac{( - 3)}{10} ] = ( \frac{2}{3} + \frac{2}{7} ) - \frac{3}{10} \\ \\ \frac{2}{3} + [ \frac{20 - 21}{70} ] = \frac{14 +6 }{21} - \frac{3}{10} \\ \\ \frac{2}{3} - \frac{1}{70} = \frac{20}{21} - \frac{3}{10} \\ \\ \frac{140 - 3}{210} = \frac{200 - 63}{210} \\ \\ \frac{137}{210} = \frac{137}{210}$

Hence proved!
