Question

Simplify: (4 /5 + 6/ 25 ) X (8/ 9 + −8 /7 )​

Answer 1

Answer: -416/1575

Step-by-step explanation:

$\frac{4}{5}=\frac{20}{25} \implies \frac{4}{5}+\frac{6}{25}=\frac{26}{25}$

$\frac{8}{9}=\frac{56}{63}\\\\-\frac{8}{7}=-\frac{72}{63}\\\\\implies \frac{8}{9}-\frac{8}{7}=-\frac{16}{63}$

$\frac{26}{25} \times -\frac{16}{63}=-\frac{416}{1575}$
