If you do 2/5+17+19+20=100 What is the average number help ples
@DrBob222 I dont understand either. She wants us to find the median but I dont know the median of 100.
I don't get it. That's an inequality. the left side is not equal to the right side. I don't understand what you want.
A math tutor may know what this is.
If you just have a list of numbers, such as
2/5, 17, 19, 20, 100
then the mean is the sum, divided by how many there are. In this case, that would be
(2/5+17+19+20+100)/5 = 31.28
The median is the middle value, when they are sorted. For this list, that would be 19
That fraction in there seems to be a typo to me. If so, fix things up and then just follow the steps I outlined.
But I'm confused because those numbers on the left are NOT equal to 100. Perhaps the = sign is a typo.
To find the average, you need to sum up all the numbers and divide the total by the count of numbers given.
In this case, you have 4 numbers: 2/5, 17, 19, and 20.
Now, let's calculate the sum of these numbers:
2/5 + 17 + 19 + 20 = ?
To add fractions, you need to have a common denominator. Since the other numbers are integers, you can convert 2/5 to a fraction with a common denominator of 5:
2/5 = 2 * 1/5 = 2/5
Now, calculate the sum:
2/5 + 17 + 19 + 20 = 2/5 + 17 + 19 + 20
Next, add the numbers together:
= (2 + 5 * 17 + 5 * 19 + 5 * 20) / 5
= (2 + 85 + 95 + 100) / 5
= 282 / 5
= 56.4
So, the sum of the numbers is 56.4.
To find the average, divide the sum by the count of numbers:
Average = 56.4 / 4
Average ≈ 14.1
Therefore, the average of the numbers 2/5, 17, 19, and 20 is approximately 14.1.
