  1. A mixed number is a whole and a fraction stuck together. Deal with them separately — wholes with wholes, halves with sevenths.
  2. The fraction halves are different sizes, so cut both into 14ths first: 2 is 2 , and 2 is 2 .
  3. The fractions go together first: − = .
  4. Then the wholes: 2 − 2 = 0.
  5. So the answer is .

How it works.

  1. 01

    A mixed number is a whole and a fraction stuck together. Deal with them separately — wholes with wholes, halves with sevenths.

  2. 02

    The fraction halves are different sizes, so cut both into 14ths first: 2 1/2 is 2 7/14, and 2 1/7 is 2 2/14.

  3. 03

    The fractions go together first: 7/14 − 2/14 = 5/14.

  4. 04

    Then the wholes: 2 − 2 = 0.

  5. 05

    So the answer is 5/14.
