How to subtract the matrices?</h3>
The subtraction of two matrices of the same size is really direct. You just need to subtract the elements that are in the same position, then:
![A = \left[\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\end{array}\right] \\\\B = \left[\begin{array}{ccc}b_{11}&b_{12}\\b_{21}&b_{22}\end{array}\right]\\\\A - B = \left[\begin{array}{ccc}a_{11} - b_{11}&a_{12}-b_{12}\\a_{21} - b_{21}&a_{22}-b_{22}\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da_%7B11%7D%26a_%7B12%7D%5C%5Ca_%7B21%7D%26a_%7B22%7D%5Cend%7Barray%7D%5Cright%5D%20%5C%5C%5C%5CB%20%3D%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Db_%7B11%7D%26b_%7B12%7D%5C%5Cb_%7B21%7D%26b_%7B22%7D%5Cend%7Barray%7D%5Cright%5D%5C%5C%5C%5CA%20-%20B%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da_%7B11%7D%20-%20b_%7B11%7D%26a_%7B12%7D-b_%7B12%7D%5C%5Ca_%7B21%7D%20-%20b_%7B21%7D%26a_%7B22%7D-b_%7B22%7D%5Cend%7Barray%7D%5Cright%5D)
Then the missing therm will just be equal to the difference between the last two elements of each matrix:
-2 - (-6) = -2 + 6 = 4
The missing number is 4.

Hello from MrBillDoesMath!

Thank you,
MrB
1/4 + 3/10 = 10/40 + 12/40 = 22/40
40/40 = 22/40 = 18/40
18/40 = cranberry j
Ratio=
A : O : C
10/40 : 12/40 : 18/40
0.25 : 0.3 : 0.45
