Multiply Mixed Numbers
1. The problem is to multiply the mixed numbers $-3 \frac{1}{4}$ and $2 \frac{2}{3}$.
2. Convert each mixed number to an improper fraction.
- $-3 \frac{1}{4} = -\left(3 + \frac{1}{4}\right) = -\frac{13}{4}$.
- $2 \frac{2}{3} = 2 + \frac{2}{3} = \frac{6}{3} + \frac{2}{3} = \frac{8}{3}$.
3. Multiply the improper fractions:
$$-\frac{13}{4} \times \frac{8}{3} = -\frac{13 \times 8}{4 \times 3} = -\frac{104}{12}$$
4. Simplify the fraction $-\frac{104}{12}$ by dividing numerator and denominator by their greatest common divisor $4$:
$$-\frac{104 \div 4}{12 \div 4} = -\frac{26}{3}$$.
5. Convert back to a mixed number:
- Divide $26$ by $3$: $26 \div 3 = 8$ remainder $2$.
- So, $-\frac{26}{3} = -8 \frac{2}{3}$.
Final answer: $-8 \frac{2}{3}$.
