# Out of 20 attempts, a basketball player scored 8 times. What percent of his chances did he score?

The word (times) makes think I should multiply and get 16% but I know that is not right when the answer is 40%. What is the simple form I can work it without a calculator and still get the the right answer.

8/20 = 4/10 = 40%

He scored 8 times out of 20 so that is 8/20. To simple find the percentage all you need to do is multiply 8/20 by 5 because that will make 100%. You just need to think what you can multiply a number by to make 100.
8*5 / 20*5
=40/100 OR 40%.

An alternative is to divide 8 by 20: 8/20.
8/20
=0.4 ——> Since 0.4 is also the same as 40%, you still get the right answer.

8/20 = .4 or 40 percent

Just do the number of successes divided by the number of attempts. This works for many statistical measures.

Examples:

I flipped a coin 5 times, and I got heads twice.
2 makes / 5 attempts = 40 percent

I rolled a die 10 times and rolled a two 1 time
1 make / 10 attempts = 10 percent

8/20*100=40%

all you do is divide 20 by 8, which is .40 = 40%
