Answer 3

To evaluate the expression 3 • (1/3 - 1/6 • y) when y = -3, we can substitute the value of y into the expression and simplify:

3 • (1/3 - 1/6 • (-3))

First, let's simplify the expression inside the parentheses:

1/3 - 1/6 • (-3) = 1/3 - 1/6 • 3

Multiplying 1/6 by 3 gives us:

1/3 - 1/2

Now, we need to find a common denominator for 1/3 and 1/2, which is 6:

1/3 = 2/6

Therefore, the expression becomes:

2/6 - 1/2

Now, let's find a common denominator for 2/6 and 1/2, which is 6:

2/6 - 1/2 = 2/6 - 3/6

Subtracting the fractions:

2/6 - 3/6 = -1/6

Therefore, 3 • (1/3 - 1/6 • y) when y = -3 is equal to -1/6.
