If you recieved a score of 80% on an assignment, what is the ratio of correct answers to incorrect anwers?

1 answer:

7 0

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!

one would say that the simple interest doubles if the period of time is specified in the contract and the contract is still valid, if the interest amount is available anitime and so on.

So if the amount doubles let's say at half time for which the principal was awarded to the bank, by the end of the contract , the interest amount can be double × just increased by 1.5
