Answer 2

To solve this expression, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Here's the step-by-step solution:

Expression: -3/14 * 7 - 8/15 : (-4/5) + 51/12 * (-24)

Step 1: Solve the multiplication and division within the expression.

-3/14 * 7 = -21/14 = -3/2 -8/15 : (-4/5) = -8/15 * (-5/4) = 2/3 * 5/4 = 10/12 = 5/6 51/12 * (-24) = (51/12) * (-24/1) = (-17/4) * (-24) = 102/1 = 102

Now, the expression becomes:

-3/2 - 5/6 + 102

Step 2: Combine like terms by finding a common denominator.

-3/2 = -9/6 (common denominator is 6)

Now, the expression becomes:

-9/6 - 5/6 + 102

Step 3: Subtract the fractions:

(-9/6 - 5/6) = -14/6 = -7/3

Finally, add the result to 102:

-7/3 + 102

Step 4: Convert -7/3 to a mixed number (optional):

-7/3 can be expressed as a mixed number: -2 1/3

Now, the expression becomes:

-2 1/3 + 102

Step 5: Add the fractions and the whole number:

-2 1/3 + 102 = -2 1/3 + 306/3 = (-2 + 306)/3 = 304/3

So, the final answer is 304/3.
