Answer 2

To solve this expression, we'll follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

Step 1: Simplify within the parentheses: 8/15 * (-1/2) = -4/15

Step 2: Simplify the division: -3/10 ÷ (-6/5) = -3/10 * (-5/6) = 1/4

Now we have: -4/15 - 1/4

Step 3: Find a common denominator for the fractions, which is 60:

-4/15 = -16/60 1/4 = 15/60

Now the expression becomes: -16/60 - 15/60

Step 4: Combine the fractions: -16/60 - 15/60 = (-16 - 15) / 60 = -31/60

The final result of the expression is -31/60, which can be simplified further if needed.
