Average = Mean
To find the mean, add up the numbers and divide it by how many numbers there are.
So, [tex]-2.6+1.8+(-3.3)+(-2.7)+2.2=-4.6[/tex]
There are 5 numbers in total.
[tex]-4.6 \div 5=-0.92[/tex]
To do these types of division, ignore the decimal and add a 0 at the end.
So we can do:
[tex]-460\div5=-92[/tex]
And put back the decimal.
Hope this helps :)
