Answer: 6.75

Step-by-step explanation:

      To find the arithmetic mean, we add the numbers together and divide by the number of numbers. 9 plus 4.5 is 13.5. Dividing this by 2 gives us 6.75.

             [tex]\displaystyle \frac{9+4.5}{2} =\frac{13.5}{2} =6.75[/tex]

      You will see that we end up with an answer of 6.75, giving us the arithmetic mean.

Answer:

Step-by-step explanation:

First thing is to bring up the decimal to the top. Just move it straight up. It will be part of the answer now. Divide 13 by 2 to get 6. Since 13 / 2 = 6, then 6 times 2 is 12 and that goes below the 13 and subtract. We end up with a 1. Bring down the 5 and now divide 15 by 2 to get 7. Put that up top. 7 times 2 is 14 and that goes below the 15 and subtract. We end up with a 1 again. As you can see in the attachment, I put a 0 inside the division box in pink and brought it down next to the 1 and now that allows us to divide 10 by 2, which divides evenly. 10/2 = 5 so that goes up top. And you're done!
