Answer 2

To solve the expression $-4 \frac{6}{7} + (-2 \frac{3}{7})$, we'll follow these steps:

Step 1: Convert mixed numbers to improper fractions. Step 2: Perform the addition. Step 3: Simplify the result if necessary.

Let's start with step 1:

$-4 \frac{6}{7}$ as an improper fraction: $-4 \frac{6}{7} = -\left(4 + \frac{6}{7}\right) = -\left(\frac{28}{7} + \frac{6}{7}\right) = -\frac{34}{7}$

$-2 \frac{3}{7}$ as an improper fraction: $-2 \frac{3}{7} = -\left(2 + \frac{3}{7}\right) = -\left(\frac{14}{7} + \frac{3}{7}\right) = -\frac{17}{7}$

Now, let's proceed to step 2:

$-\frac{34}{7} + (-\frac{17}{7}) = -\frac{34}{7} - \frac{17}{7} = -\frac{51}{7}$

Now, in step 3, we see that $-\frac{51}{7}$ is already in its simplest form.

So, $-4 \frac{6}{7} + (-2 \frac{3}{7}) = -\frac{51}{7}$.
