Answer 2

To divide a fraction by a mixed number, you can follow these steps:

1. Convert the mixed number to an improper fraction.
2. Flip the divisor (the number you're dividing by).
3. Multiply the dividend (the first fraction) by the flipped divisor.

Let's apply these steps to your problem:

1. Convert the mixed number (-1 2/7) to an improper fraction: -1 2/7 = (-1 * 7) + 2 / 7 = -7/7 + 2/7 = -5/7

2. Flip the divisor: The flipped divisor is -5/7.

3. Multiply the dividend (4/7) by the flipped divisor (-5/7): (4/7) * (-5/7) = (4 * -5) / (7 * 7) = -20/49

So, 4/7 ÷ (-1 2/7) = -20/49.
