Hi ppl i rlly need i’ve been off school and i rlly need to know the mean of 263 240 and 256 also i need to know the mean of 12 13 and 17 ty i may need to know how to work the mean out of three numbers too

So the mean of 263,240,256 is 253 and the mean of 12,13,17 is 14

Step-by-step explanation:

To get the mean of these numbers you add all three of them together then you divide them by the amount of numbers so you are going to add 263+240+256=759 then you divide by 3
