Convert 15 2/3 to an improper fraction;

- 15 × 3 + 2/3 - 5 2/3

Simplify 15 × 3 to 45

- 45 + 2/3 - 5 2/3

Simplify 45 + 2 to 47

- 47/3 - 5 2/3

Convert 5 2/3 to an improper fraction

- 47/3 - 5 × 3 + 2/3

Simplify 15 + 2 to 17

- 47/3 - 17/3

Join the denominators

-47 - 17/3

Simplify

- 64/3

Convert to a mixed fraction;

<u>-21 \frac{1}{3}</u>
