5th Grade Average Practice Problems and Worksheets

Let's solve this problem step-by-step:

• Step 1: Count the balls.
  In the provided diagram, we need to count each ball shown to obtain the total number.
• Step 2: Determine the number of columns.
  The table's columns are evenly spaced, and there appears to be 4 columns depicted.
• Step 3: Calculate the number of balls per column.
  Divide the total number of balls by the number of columns.

Step 1: Count the balls.

There are 20 balls depicted in the diagram.

Step 2: Determine the number of columns.

There are 4 columns in the table based on the grid lines visible in the diagram.

Step 3: Perform the division.

The formula to find the number of balls per column is: $\frac{\text{total number of balls}}{\text{number of columns}} = \frac{20}{4} = 5$.

Thus, there will be 5 balls in each column.

Let's work through these steps:
Step 1: Count the balls. We have a total of 12 balls displayed in the image.
Step 2: Count the columns. There are 4 columns shown in the SVG.
Step 3: Divide the total number of balls (12) by the number of columns (4).

Performing the division yields: $\frac{12}{4} = 3$

Therefore, each column will contain 3 balls.

The average of a set of numbers is found by dividing the sum of the numbers by how many numbers there are.

Let's find the average of the numbers $20$, $0$, and $7$:

• Step 1: Calculate the sum of the numbers:
  $20 + 0 + 7 = 27$.
• Step 2: Count how many numbers there are. Here, we have 3 numbers.
• Step 3: Apply the average formula:
  $\text{Average} = \frac{27}{3}$.
• Step 4: Divide the sum by 3:
  $\frac{27}{3} = 9$.

Therefore, the average of 20, 0, and 7 is $9$.

To calculate the average of the numbers 20 and 10, we will follow these steps:

• Step 1: Add the two numbers together. We have $20 + 10 = 30$.
• Step 2: Divide the sum by the number of values, which is 2. So, we have $\frac{30}{2} = 15$.

Therefore, the average of 20 and 10 is $15$.

To calculate the average of the numbers 2, 6, 8, and 4, we will follow these steps:

• Step 1: Calculate the sum of the numbers.

The numbers given are $2$, $6$, $8$, and $4$. Therefore, we find the sum as follows:

$2 + 6 + 8 + 4 = 20$.

• Step 2: Count the number of numbers.

We have a total of 4 numbers.

• Step 3: Calculate the average by dividing the sum by the count.

The average is calculated by dividing the total sum by the count of the numbers:

$\text{Average} = \frac{20}{4} = 5$.

Thus, the average of the numbers $2$, $6$, $8$, and $4$ is $\boxed{5}$.
