Question

Find the average for the following numbers:

A) 12 11 1/2 11 2/8
B) 11 7 9
C) 12 13 10

Answer 1

finding the average is basically adding up all of the numbers and then dividing it by how many numbers there were on the data set.

e.g.

find the average of 10, 20, 30

\[\large \frac{ 10 + 20 + 30 }{ 3 } =\frac{ 60 }{ 3 } = 20\]
so 20 is the average from this example data set

Answer 2

I know. But A is confusing for me...

Answer 3

\[\large \frac{ 12 + 11 \frac{ 4 }{ 8 } 11 \frac{ 2 }{ 8 } }{ 3 }\]

Answer 4

notice how i changed 11 1/2 to 11 4/8

Answer 5

34 6/8

Answer 6

no 34 3/4

Answer 7

\[\frac{ 6 \div 2 }{ 8 \div 2 } = \frac{ 3 }{ 4 }\]

Answer 8

Oh yeah. My bad. I got carried away.

Answer 9

The next step would be dividing that by 3.

Answer 10

yes

Answer 11

That's where I got stuck...

Answer 12

Answer 13

Tip: \(\huge \frac{ 3 }{ 4 }\) can also be written as \(\huge 0.75\).

Answer 14

Yeah...I know, but I do not see how that can help?

Answer 15

Oh really? You don't know how to do this? Okay...

Answer 16

Humiliating me doesn't help either.
