Let's assume, for simplicity, that there were 100 questions in the test: a score of 80% means you got 80 right and (100-80)=20 wrong.
The ratio is then 80 to 20 or
80:20.
you can also simplyfy it, by dividing both numbers by 20:
4:1
which I think is the best way to give the answer!

The solution for s in the given equation is 
The question seems to be incomplete
Here is the complete question:
Solve for s in this equation 
Depreciation.
To solve for s, that means we should make s the subject of the equation
From the given equation,
To solve for s, first multiply both sides by n to clear the fraction
We get
Then,
Now, add s to both sides
Then, subtract nD from both sides
∴
Hence, the solution for s in the given equation is

Answer:
The interest on the savings account is $46.47
Step-by-step explanation:
Here, we want to know the interest earned on the savings account.
The difference between the new and previous balance will be; 12,098.12 - 9,053.20 = $3,044.92
The difference between amount deposited and amount withdrawn is 3,298.45 - 300 = 2,998.45
This is the amount that is supposed to be on the account without interest
So the interest earned would be; 3044.92 - 2,998.45 = $46.47
