1)
$\frac{3}{7} x = 1 \\ \frac{7}{3} \times \frac{3}{7}x = \frac{7}{3} \\ x = \frac{7}{3} \\ x = 2 \times \frac{1}{3}$
2)
$1.8x = 1 \\ 1.8x \div 1.8 = 1 \div 1.8 \\ x = 1 \div \frac{9}{5} \\ x = \frac{5}{9}$
3)
$\frac{11}{18} x = 1 \\ \frac{18}{11} \times \frac{11}{18} x = \frac{18}{11} \\ x = \frac{18}{11} \\ x = 1 \times \frac{7}{11}$
4)
$1 \times \frac{1}{3} \times y = 1 \\ \frac{4}{3} y = 1 \\ \frac{3}{4} \times \frac{4}{3} y = \frac{3}{4} \\ y = \frac{3}{4}$
5)
$0.6y = 1 \\ 0.6y \div 0.6 = 1 \div 0.6 \\ y = 1 \div \frac{3}{5} \\ y = \frac{5}{3} \\ y = 1 \times \frac{2}{3}$
6)
$2.4y = 1 \\ 2.4y \div 2.4 = 1 \div 2.4 \\ y = 1 \div \frac{12}{5} \\ y = \frac{5}{12}$
