A matrix is diagonal if

i\neq j \implies A_{i,j}=0

In other words, you want non-zero elements only when the indices of the row and the column are the same: the first element of the first row must be non zero, the second element of the second row must be non-zero, and so on. All other elements must be zero.

The percentage decrease was by 
percentage decrease = ((b-a)/b)*100
b is the original value
a is the other value
p= ((1150-230)/1150)*100

p = (0.8) * 100
p = 80

The percentage decrease is 80% from 1150 to 230 lbs of flour.

Hope this helps :)
