▪5)

$\frac{7}{15} x = 1 \\ x = 1 \div \frac{7}{15} = 1 \times \frac{15}{7} = 2 \frac{1}{7} \\ x = 2 \frac{1}{7}$

▪6)

$3 \frac{2}{3} x = 1 \\ x = 1 \div \frac{11}{3} = \frac{3}{11} \\ x = \frac{3}{11}$

▪7)

$100x = 1 \\ x = \frac{1}{100} \\ x = 0.01$

▪8)

$\frac{2}{13} x = 1 \\ x = \frac{13}{2} = 6 \frac{1}{2} \\ x = 6 \frac{1}{2} = 6.5$
