Answer:
65 - 13n/20n
Step-by-step explanation:
Lets say you are on number 1.
You would do...
([tex]\frac{4n}{n^{2} }[/tex] - [tex]\frac{4n}{5n}[/tex]) - ([tex]\frac{3}{4n} - \frac{3}{20}[/tex])
From this you would simplify more by doing 4n/n^2
That would be just 4/n.
And simplify through the whole problem.
