Answer:
[tex]\frac{45y}{56x}[/tex]
Step-by-step explanation:
[tex]\frac{5}{-7x} times \frac{-9y}{8}[/tex]
When we multiply two fractions we multiply numerator with numerator and denominator with denominator
5 times -9y is -45y
Then -7x times 8 is -56x
So the fraction becomes [tex]\frac{-45y}{-56x}[/tex]
we have negative at the top and bottom so it becomes positive
[tex]\frac{45y}{56x}[/tex]
We cannot simplify further
