Answer 1

2/5

Explanation:

First, replace the variables with their respected value.

2(-4/5) + 6(1/3)

Second, use GEMDAS (Grouping, Exponents, Multiplication, Division, Addition, Subtraction) and solve the multiplication first.

2(-4/5) = -8/5

6(1/3) = 2

-8/5 + 2

Lastly, add them together. I recommend making -8/5 into a mixed number before adding them together.

-8/5 = -1 3/5

-1 3/5 + 2

-3/5 + 1

2/5
