Answer 2

To solve these division problems, we'll first convert any mixed numbers to improper fractions, and then apply the division operation.

1. $\frac{7}{9} \div \frac{7}{3}$

Convert the mixed number to an improper fraction: $2 \frac{1}{3} = \frac{7}{3}$

Now, rewrite the division as multiplication by the reciprocal: $\frac{7}{9} \div \frac{7}{3} = \frac{7}{9} \times \frac{3}{7}$

Multiply the fractions: $\frac{7 \times 3}{9 \times 7} = \frac{21}{63}$

Simplify the fraction: $\frac{21}{63} = \frac{1}{3}$

2. $\frac{11}{19} \div \frac{80}{57}$

Rewrite the division as multiplication by the reciprocal: $\frac{11}{19} \times \frac{57}{80}$

Multiply the fractions: $\frac{11 \times 57}{19 \times 80} \approx \frac{627}{1520}$

Simplify the fraction (divide both numerator and denominator by their greatest common divisor): $\frac{627}{1520} \approx \frac{261}{630}$

3. $3 \frac{1}{5} \div \frac{24}{35}$

Convert the mixed number to an improper fraction: $3 \frac{1}{5} = \frac{16}{5}$

Rewrite the division as multiplication by the reciprocal: $\frac{16}{5} \times \frac{35}{24}$

Multiply the fractions: $\frac{16 \times 35}{5 \times 24} = \frac{560}{120}$

Simplify the fraction (divide both numerator and denominator by their greatest common divisor): $\frac{560}{120} = \frac{14}{3}$
