There is a piece of information missing.
How many mL is a teaspoon?

kpoplove2289 · Answer

There is 5mL per teaspoon.

mathstudent55 · Answer

Ok.
Then we have this:
80 mg per 2.5 mL
Multiply the above ratio by 2 and you get:
160 mg per 5 mL

i think the equation that we use is ordered dosage over dosage has times quantity. Because the answer is 1 teaspoon, but I dont understand how to get that.

Look at what I just showed you above.
I'll explain it again.
A 2.5 mL dose of this medicine has 80 mg of acetaminophen
Since you need 160 mg of acetaminophen, which is exactly twice 80 mg, you need to double the dose.

mathstudent55 · Answer

That means you need 
a 5 mL dose of medicine to have 160 mg of acetaminophen.
Since you told me that a teaspoon is 5 mL, that means you need a dose of 1 teaspoon to have 160 mg of acetaminophen.
