guess what property is used:

[tex] \frac{-4}{7} + \frac{5}{8} = \frac{5}{8} + ( \frac{ - 4}{7} )[/tex]
[tex]( \frac{1}{2} \times \frac{4}{7} ) \times ( \frac{ - 2}{3} )= \frac{1}{2} \times ( \frac{4}{7} \times ( \frac{ - 2}{3} ))[/tex]
7/-8 x (-8/7)=1

i will mark u brainliest if u answer this correctly​
