Answer 2

To solve this expression, you should 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). In this expression, you have multiplication and subtraction, so you should perform these operations from left to right.

Let's break it down step by step:

1. First, perform the multiplications from left to right: 3 * (5/14) = 15/14 (45/14) * (7/9) = (45 * 7) / (14 * 9) = 315/126 = 105/42 = 5/2

2. Now, you have the expression in terms of fractions: (15/14) - (5/2)

3. To subtract these fractions, you need a common denominator, which is 14 in this case. Adjust the fractions accordingly: (15/14) - (5/2) = (15/14) - (35/14)

4. Now, subtract the fractions with the common denominator: (15/14) - (35/14) = (15 - 35)/14 = (-20)/14

5. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2: (-20/2) / (14/2) = -10/7

So, the final result is -10/7.
