The mean could be 5, 5, 5, 5,. If u add them all up you get 20. Divide them by 4 and you get 5.
It is: 20/5 = 4
It's a way to reduce fractions. If you wanted to reduce 20/24 and you knew that the GCF of 20 and 24 was 4, you would divide 20 and 24 by 4 and get 5 and 6. 20/24 = 5/6
The factors of 20 are 1, 2, 4, 5, 10 and 20, the positive integers that divide evenly into 20 with no remainder.
divide 20 by 5 = 4 divide 25 also by 5 = 5 4/5
4
5/20 = 1/4 = 0.25
First, you add up 3, 6, 5, 4, and 2. Which is 20. Then, you had 5 numbers, so divide 20 by 5. Which equals 4. That is your mean, which is basically an average of many numbers.
1, 2, 4, 5, 10, and 20 divide evenly into 20.
These numbers divide 20 equally: 1, 2, 4, 5, 10, 20.
divide a number by 5, the answer is 20%
