Question

Answer 1

○○○○○○○○○○○○○○○○○○○○○○

Answer 2

$7.2 \div 3 \frac{2}{5} = x \div 1 \frac{1}{2} \\ \frac{36}{5} \times 1 \frac{1}{2} = 3 \frac{2}{5} \times x \\ \frac{36}{5} \times \frac{3}{2} = \frac{17}{5} x \\ \frac{18}{5} \times 3 = \frac{17}{5} x \\ \frac{54}{17} = x \\ x = \frac{54}{17} = 3 \frac{3}{17}$
