To solve the proportion \( \frac{x}{5} = \frac{8}{9} \), you can use cross-multiplication.
Cross-multiplying gives:
\[
x \cdot 9 = 5 \cdot 8
\]
This simplifies to:
\[
9x = 40
\]
Now, divide both sides by \( 9 \) to solve for \( x \):
\[
x = \frac{40}{9}
\]
So, the solution is:
\[
x = \frac{40}{9}
\]
Cross-multiplying gives:
\[
x \cdot 9 = 5 \cdot 8
\]
This simplifies to:
\[
9x = 40
\]
Now, divide both sides by \( 9 \) to solve for \( x \):
\[
x = \frac{40}{9}
\]
So, the solution is:
\[
x = \frac{40}{9}
\]
