Please see the attached pictures for the full solution.
*I evaluated the determinants using Sarrus' rule (see last picture):
∆= aei +bfg +cdh -gec -hfa -idb
*The symbol '∆' (delta) is usually used to denote a determinant.

I can't add picture for some reason so u have to read explanation :(
Step-by-step explanation:
First, turn everything into an improper fraction.
you get 11/3 x 9/2 ÷ 5/4
Next, according to PEMDAS, you multiply first and you get
33/2. DIvide that by 5/4 so
33/2 ÷ 5/4
So you get 33/5 or as a mixed fraction, 6 3/5
In any hexagon, the interior angles add to 720 degree
Answer:
Step 1 - Find Whole Number
Calculate out how many times the denominator goes into the numerator. To do that, divide 385 by 6 and keep only what is to the left of the decimal point:
385 / 6 = 64.1667 = 64
Step 2 - Find New Numerator
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
385 - (6 x 64) = 1
Step 3 - Get Solution
Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 385/6 as a mixed number is:
64 1
