Answer 1

13 × ( – 2 / 11) + 9 × ( – 2 / 11) = -2\11 * (13+9)= -2\11 *22=-(2*22)\11=-44\11=-4

Answer 3

To solve this expression, you need to follow the order of operations, which is often remembered using the acronym PEMDAS:

1. Parentheses
2. Exponents (Powers and Roots)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the expression step by step:

1. Begin with the multiplication inside the parentheses: -2 / 11 = -0.18181818... (repeating decimal)

2. Now, multiply the result by 13 and 9: 13 * (-0.18181818...) = -2.36363636... (repeating decimal) 9 * (-0.18181818...) = -1.63636363... (repeating decimal)

3. Finally, add the two results together: -2.36363636... + (-1.63636363...) = -4.00000000...

So, the final result of the expression is -4.
