  1. a equals 10 minus fraction numerator k over denominator n b end fraction
  2. a equals 10 minus fraction numerator n b over denominator k end fraction
  3. a equals fraction numerator 10 minus k over denominator n b end fraction
  4. a equals fraction numerator 10 minus n b over denominator k end fraction

The correct answer is: a equals fraction numerator 10 minus n b over denominator k end fraction
