Question

-4/5 × 5/7 × -8/9 +8/9 × 4/7​

Answer 1

$\frac{ - 4}{5} \times \frac{5}{7} \times \frac{ - 8}{9} + \frac{8}{9} \times \frac{4}{7} \\ = \frac{ - 4}{7} \times \frac{ - 8}{9} + \frac{8}{9} \times \frac{4}{7} \\ = \frac{32}{63} + \frac{32}{63} \\ = \frac{32 + 32}{63} \\ = \frac{64}{63}$

Answer 2

Step-by-step explanation:

-4/5×5/7×-8/9=160/315

8/9×4/7=32/63

Required =160/315+32/63

=(10080+10080)/19845

=20160/19845

=1.0158
