To solve the proportion given in the image:

$\frac{9}{11} = \frac{y}{7}$

We can solve for $y$ by cross-multiplying:

$9 \times 7 = 11 \times y$

This simplifies to:

$63 = 11y$

Now, divide both sides by 11 to solve for $y$:

$y = \frac{63}{11} \approx 5.73$

Thus, $y \approx 5.73$.

Tip: When solving proportions, always cross-multiply to eliminate the fractions and isolate the variable.
