Answer 2

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

P: Parentheses E: Exponents MD/AS: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

Let's break down the expression step by step:

Step 1: Evaluate what's inside the parentheses first. (2,3 + 5 1/3) can be converted into a mixed fraction: 2 + 3/1 + 5 + 1/3 = 2 + 3 + 5 + 1/3 = 10 + 1/3

Step 2: Now let's evaluate the subtraction inside the parentheses: 8/15 - (10 + 1/3) - 1 2/15

Step 3: Combine the whole numbers and fractions separately: 10 + 1/3 can be converted into a mixed fraction: 10 + 1/3 = 30/3 + 1/3 = 31/3

1 2/15 can be converted to an improper fraction: 1 2/15 = 17/15

Step 4: Now we can subtract: 8/15 - 31/3 - 17/15

Step 5: Find a common denominator (which is 15) for the fractions: 8/15 - (31/3 * 5/5) - 17/15 8/15 - 155/15 - 17/15

Step 6: Subtract the fractions: (8 - 155 - 17) / 15 (-164) / 15

The final result is: -164 / 15 or approximately -10.93
