Answer 2

To simplify the expression, let's perform the calculations step by step:

1. Simplify the first term: -0.25a * (-4) When multiplying a number by a negative value, the result will be positive. Therefore, -0.25a * (-4) becomes 1a (or simply "a").

2. Simplify the second term: 5/6 * (12a - 3) To simplify this fraction, we need to distribute the 5/6 to both terms inside the parentheses:

   5/6 * 12a = (5 * 12 * a) / 6 = 60a / 6 = 10a 5/6 * (-3) = (5 * -3) / 6 = -15 / 6 = -2.5

   So, the second term becomes 10a - 2.5.

Now, we can combine the simplified terms:

a + 10a - 2.5

Combine the "a" terms:

1a + 10a = 11a

The simplified expression is:

11a - 2.5
