Question

evaluate using appropriate properties 5/7×-2/3+5/7×-1/9​

Answer 1

Step-by-step explanation:

$\frac{5}{7} \times \frac{ - 2}{3} + \frac{5}{7} \times \frac{ - 1}{9} \\ = \frac{ - 10}{21} + \frac{ - 5}{63} \\ = \frac{ - 30 + ( - 5)}{63} \\ = \frac{ - 30 - 5}{63} \\ = \frac{ - 35}{63} \\ = \frac{ - 5}{9}$
