Answer 2

`\bf \begin{array}{cccccclll} &\cfrac{3}{2}&\cfrac{6}{4}&\cfrac{9}{6}&\cfrac{12}{8}&\cfrac{x}{10}\\\\ &\uparrow &\uparrow &\uparrow &\uparrow &\uparrow \\ ratios&\cfrac{3}{2}&\cfrac{3}{2}&\cfrac{3}{2}&\cfrac{3}{2}&\cfrac{3}{2} \end{array} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{3}{2}=\cfrac{x}{10}\implies 30=2x\implies \cfrac{30}{2}=x\implies 15=x`
