Explanation:

Step1: Solve for first missing value

We know $18 \times x = 180$. Rearrange to solve for $x$:
$x = \frac{180}{18} = 10$

Step2: Solve for second missing value

We know $18 \times y = 180$. Rearrange to solve for $y$:
$y = \frac{180}{18} = 10$

Step3: Solve for third missing value

We know $18 \times z = 90$. Rearrange to solve for $z$:
$z = \frac{90}{18} = 5$

Step4: Solve for fourth missing value

We know $18 \times w = 18$. Rearrange to solve for $w$:
$w = \frac{18}{18} = 1$
