Answer 2

To solve the expression $-2 + \left(\frac{11}{18} + \frac{4}{9}\right) \div 2 \frac{1}{9} - \frac{3}{7}$, 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 it down step by step:

1. Simplify within parentheses: $-2 + \left(\frac{11}{18} + \frac{4}{9}\right) \div 2 \frac{1}{9} - \frac{3}{7}$

   $-2 + \left(\frac{11}{18} + \frac{8}{18}\right) \div 2 \frac{1}{9} - \frac{3}{7}$

   $-2 + \frac{19}{18} \div 2 \frac{1}{9} - \frac{3}{7}$

2. Simplify the fraction within parentheses: $-2 + \frac{19}{18} \div 2 \frac{1}{9} - \frac{3}{7}$

   $-2 + \frac{19}{18} \div \frac{19}{9} - \frac{3}{7}$

3. Divide by multiplying by the reciprocal: $-2 + \frac{19}{18} \times \frac{9}{19} - \frac{3}{7}$

   $-2 + 1 - \frac{3}{7}$

4. Combine like terms: $-1 - \frac{3}{7}$

5. Find a common denominator for subtraction: $-\frac{7}{7} - \frac{3}{7}$

6. Perform subtraction: $-\frac{10}{7}$

So, the result of the expression is $-\frac{10}{7}$.
