(20 + 3 + 5 + 6)/4 = 34/4 = 8.5
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.
5/6 of 20 20/6=3 1/3 3 1/3 * 5= 17 2/3
The mean is the same thing as average. To get the mean you add together all of the numbers in the set. Then, you divide by the total amount of numbers that were added to get the mean/average. Example: Find the mean of 5, 4, 6, 3, and 2. 5+4=9+6=15+3=18+2=20 1 2 3 4 5 (There are a total of five numbers in the set.) 5 4 6 3 2 - Numbers of the set. 20 (Sum of all numbers in the set) Divided by: 5 (Amount of numbers in the set) equals: 4 The mean (or average) of 5, 4, 6, 3, and 2 is 4.
2*3=6 5*4=20 answer is 6/20
They are: 6/10, 12/20 and 24/40
The mean is always the sum of the values divided by how many you have. Here the mean is : (8+5+2+6+3+6)/6 = 5
6 2/5 - 5 3/4 = 13/20 6 and 2/5 becomes 128/20 5 and 3/4 becomes 115/20 Subtract the numerators and you have your answer. Or, 6 2/5 = 6.4 and 5 3/4 = 5.75 6.4 - 5.75 = .65 .65 = 13/20
if you mean 2/3 of 5/6, then the answer is 5/9
(4+5+6)/3 = 15/3 = 5
4 x 5 + 6 - 3!
You can conclude that 3 out of 5 and 12 out of 20 are equivalent.
