Regardless of left-to-right, Multiplication always takes precedence over Division, as Addition always does over Subtraction. You must simplify it into the most basic terms before performing the "left-to-right" mathematics. The correct order is as follows:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
Applying that to the equation: 6/2*(1+2) will yield:
Parenthesis: 6/2*(1+2) = 6/2*(3)
Exponents: 6/2*(3)
Multiplication: 6/2*(3) = 6/6
Division: 6/6 = 1
Addition: 1 = 1
Subtraction: 1 = 1
THE ANSWER IS 1
