To subtract the two mixed numbers, you can follow these steps:

1. First, subtract the whole numbers: 15 - 7 = 8

2. Next, subtract the fractions: 7/21 - 13/21 = -6/21

3. Simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 3: -6 ÷ 3 / 21 ÷ 3 = -2/7

4. Combine the whole number and the fraction: 8 - 2/7

So, 15 7/21 - 7 13/21 is equal to 8 - 2/7.
