Below is a table describing the number of toys Jonathan has in his toy boxes.
Calculate the average number of toys in each box.
To solve this problem, we'll calculate the average number of toys in Jonathan's toy boxes using the following steps:
Let's perform the calculations:
Step 1: The number of toys in Box 1 is 3, in Box 2 is 7, and in Box 3 is 2. Therefore, the total number of toys is:
Step 2: There are 3 toy boxes. We calculate the average number of toys per box by dividing the total number of toys (12) by the number of boxes (3):
Therefore, the average number of toys in each box is .
4
Calculate the average of \( 10 \) and \( 12 \).
The total is just adding up all values (3 + 7 + 2 = 12 toys), but the mean tells you the average per box by dividing that total by the number of boxes!
We divide by 3 because that's how many toy boxes there are! The mean formula is always: total ÷ number of items. Here we have 3 boxes, so we divide by 3.
That's totally normal! If you get a decimal or fraction, that's your answer. For example, if the total was 13 toys in 3 boxes, the mean would be toys per box.
Look at your original numbers! Your mean should be between the smallest and largest values. Since we have 2, 3, and 7, our mean of 4 makes sense because 2 < 4 < 7.
No! Whether you add 3 + 7 + 2 or 2 + 7 + 3 or any other order, you'll get the same sum (12) and the same mean (4). Addition is commutative!
