Yes "3x8 = 4x6" does illustrate the commutative property of multiplication.
The digits after the decimal separator are, in order, tenths, hundreths and thousandths. So, your number is composed by:
- 1 unit
- 0 tenths
- 0 hundreths
- 2 thousandths
So, you would call this name "one and two thousandths"
The answer is -2x+11 for sure is the answer
