Let x be the amount of water you need for 2/3 cup of rice. Write a proportion using the ratio of white rice to water
$\frac{1}{2×\frac{1}{2}}=\frac{2}{\frac{3}{x}}$
$\frac{1}{\frac{5}{2}}=\frac{2}{\frac{3}{x}}$
$\frac{2}{5}=\frac{2}{3x}$
Cross multiply:
$2\left(3x\right)=5\left(2\right)$
$6x=10$
$x=\frac{10}{6}$
$x=\frac{5}{3}$
$x=1\frac{2}{3}$ cups of water.
