Use PEMDAS to figure out which expression to work out first:
Parentheses
Exponents
Multiplication/Division
Addition/Subtraction
First, we'll want to solve the term with parentheses:
[tex]2(1+3) = 2(4) = 2 \times 4 = 8[/tex]
The equation should now look like this:
[tex]6 \div 8[/tex]
Divide to get your answer:
[tex]6 \div 8 = 0.75[/tex]
The answer is 0.75.
