Question

Find whether 2\7×(-5\9 ×2\3) = (2\7 × -5\9) ×2\3​

Answer 1

Step-by-step explanation:

$\frac{2}{7} \times ( - \frac{5}{9} \times \frac{2}{3} ) = \frac{2}{7 } \times ( - \frac{10}{27} ) . \\ = \frac{ - 20}{189} \\ \\ \\ (\frac{2}{7} \times \frac{ - 5}{9} ) \times \frac{2}{3} = \frac{ - 10}{63} \times \frac{2}{3} = \frac{ - 20}{189}$

Hence proved(By cumulative property)
