$1) \frac{5}{3} x = 65 \\ x = 65 \div \frac{5}{3} \\ x = \frac{65 \times 3}{5} \\ x = 13 \times 3 = 39$

$\frac{7}{9} x = 63 \\ x = 63 \div \frac{7}{9} \\ x = \frac{63 \times 9}{7} \\ x = 9 \times 9 = 81$

$\frac{3}{7} x = \frac{6}{11} \times 44 \\ \frac{3}{7} x = 6 \times 4 \\ \frac{3}{7} x = 24 \\ x = 24 \div \frac{3}{7} \\ x = \frac{24 \times 7}{3} \\ x = 8 \times 7 = 56$
