Answer 2

To subtract the mixed numbers -9 1/6 and -7 1/14, you can follow these steps:

1. First, subtract the whole numbers: -9 - (-7) = -9 + 7 = -2

2. Next, subtract the fractions. To do this, find a common denominator, which in this case is 84 (the least common multiple of 6 and 14).

   -1/6 can be converted to -14/84 (by multiplying both the numerator and denominator by 14). -1/14 is already -6/84.

3. Subtract the fractions: -14/84 - (-6/84) = -14/84 + 6/84 = -8/84

4. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4. (-8/4) / (84/4) = -2/21

Now, combine the whole number and the fraction: -2 - 2/21

So, the result of -9 1/6 - (-7 1/14) is approximately equal to -2 2/21.
