To solve the equation \( \frac{x}{8} = \frac{y}{16} \) for \( x \) when \( y = 3 \):

  1. Substitute \( y = 3 \) into the equation:

\[ \frac{x}{8} = \frac{3}{16} \]

  1. Cross-multiply to solve for \( x \):

\[ 16x = 3 \cdot 8 \]

  1. Calculate \( 3 \cdot 8 \):

\[ 16x = 24 \]

  1. Divide both sides by 16 to solve for \( x \):

\[ x = \frac{24}{16} = \frac{3}{2} = 1.5 \]

Therefore, the value of \( x \) is 1.5 units.
