80% of 20 = 20*80/100 = 16
16 correct out of 20 questions is 80%
5 incorrect answers and 15 correct answers
There are two potential answers to that. 20 minus the value 10% is 19.90. 20 minus 10 percent of 20 is 18.
6 is 30% of 20. (I have no idea whether that answers your question.)
FourTo get 80% correct, then 20% is wrong.All 20 is 100%then 1 is 5% (divide by 20)then 4 is 20% (multiply by 4)
16 of them.
There are an infinite number of correct answers. The simplest one is 9/20 .
16 correct out of 20 questions is 80%
(18 ÷ 20) × 100 = 90 Therefore: 90%
Divide the number of correct answers by the total number of answers. If you answered 17 out of 20 questions correctly, 17/20 = 0.85 or 85%
16/20 each question is 5% so 4 wrong and 16 correct.
80
It is: 25%
It is: 55%
Both are correct, depending on the context. If decrease is a noun then decrease of is correct. eg This year we have seen a decrease of 20 percent. If decrease is a verb then decrease by 20 percent is correct. eg This year we can decrease the price by 20 percent.
6/20*100=30%
the correct aftermath to the situation/question is what the answer is.
