#Here's ur answer...☆☆☆

Step-by-step explanation:

$3.a) (\frac{4}{3} \times \frac{2}{5}) \times \frac{1}{7} = ( \frac{1}{7} \times \frac{2}{5} ) \times .... \frac{4}{3} \\ associative \: property$

$b) - 4 \times (2 + 3 + 9) = - 4 \times 2 + - 4 \\ \times 3 + - 4 \times 9 \: distributive \: property$

$c) \frac{ - 4}{9} + \frac{2}{7} = \frac{ - 4 \times 7 + 2 \times 9}{63} \\ = \frac{ - 28 + 18}{63} = \frac{ - 10}{63} (ans)$

Rational number

$d) \frac{54}{81} \times \frac{ - 63}{108} = ... \frac{ - 63}{108} \times \frac{54}{81} commutative$

$e)1 \: and \: 0 \: respectively$
