Averages for 5th Grade: Determining the average of given a sum

To solve this problem, we'll follow these steps:

• Step 1: Identify the number of values for which we are calculating the average. In this case, it is $4$.
• Step 2: Identify the given total sum, which is $20$.
• Step 3: Use the average formula to calculate: Average = $\frac{\text{Sum}}{\text{Total Count}}$.

Now, let's work through each step:
Step 1: We know that we are dealing with $4$ numbers.
Step 2: The total sum of these numbers is given as $20$.
Step 3: Using the formula for the average, we calculate:
$\text{Average} = \frac{20}{4} = 5$.

Therefore, the solution to the problem is $5$.

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information: The sum of the three numbers is $9$.
• Step 2: Apply the formula for average.
• Step 3: Perform the necessary calculation to find the average.

Now, let's work through each step:
Step 1: The problem gives us the sum of the three numbers as $9$.
Step 2: We'll use the formula for average:
$\text{Average} = \frac{\text{Sum of the numbers}}{\text{Number of values}}$ Step 3: Plugging in our values, we have: $\text{Average} = \frac{9}{3} = 3$

Therefore, the solution to the problem is $3$.

To solve this problem, we need to find the average of four numbers whose total sum is 40.

We will apply the formula for finding the average, which is:

• $\text{Average} = \frac{\text{Sum of values}}{\text{Number of values}}$

Here, the sum of the numbers is given as 40, and the number of values (numbers) is 4.

Substitute these values into the formula:

$\text{Average} = \frac{40}{4}$

Perform the division:

$\frac{40}{4} = 10$

Therefore, the average of these four numbers is $10$.

To solve this problem, we'll follow these steps:

• Step 1: Identify the given data
• Step 2: Use the average formula
• Step 3: Perform the division to find the average

Now, let's work through each step:

Step 1: The total sum of the numbers is given as $28$, and there are $7$ numbers.

Step 2: We'll use the formula for calculating the average:

$\text{Average} = \frac{\text{Sum of values}}{\text{Number of values}}$

Step 3: Plugging in the values, we have:

$\text{Average} = \frac{28}{7}$

$\text{Average} = 4$

Therefore, the solution to the problem is that the average of these seven numbers is $\mathbf{4}$.

To solve this problem, we'll apply the formula for the average:

• Step 1: The total number of numbers is $10$.
• Step 2: The sum of all these numbers is $5$.
• Step 3: Use the average formula to find the average.

Now, using the formula, the average is calculated as:
$\text{Average} = \frac{\text{Sum of all numbers}}{\text{Number of numbers}} = \frac{5}{10} = \frac{1}{2}$

Therefore, the solution to the problem is $\frac{1}{2}$.

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information
• Step 2: Apply the appropriate formula to find the average
• Step 3: Perform the calculation to find the result

Now, let's go through each step:

Step 1: The problem tells us the sum of four numbers is 15.

Step 2: We will use the formula for average: $\text{Average} = \frac{\text{Sum of numbers}}{n}$, where $n$ is the number of numbers.

Step 3: Substituting into the formula, we have:

$\text{Average} = \frac{15}{4}$

Calculating this gives:

$\frac{15}{4} = 3.75$

We can express $3.75$ as a mixed number: $3\frac{3}{4}$.

Therefore, the average of the four numbers is $3\frac{3}{4}$.

To solve this problem, we need to find the average of three numbers that sum up to 10.

We will follow these steps:

• Step 1: Identify the sum of the numbers, which is given as 10.
• Step 2: Identify the number of terms, which in this case is 3.
• Step 3: Apply the average formula $\text{Average} = \frac{\text{Sum of numbers}}{n}$.

Now, let's perform the calculations:
Step 1: The sum of the three numbers is $10$.
Step 2: There are $3$ numbers to consider.
Step 3: Calculate the average:$\text{Average} = \frac{10}{3} = 3.3333\ldots$.

We can express $3.3333\ldots$ as a mixed number: $3\frac{1}{3}$.

Therefore, the average of three numbers that sum to 10 is $3\frac{1}{3}$.
