Answer 3

To solve the proportion $\frac{9}{16} = \frac{4}{5} : \frac{9}{4}$, you can cross-multiply.

Cross-multiplying involves multiplying the numerator of the first fraction by the denominator of the second fraction and vice versa.

So, $9 \times \frac{9}{4} = 16 \times \frac{4}{5}$.

This simplifies to $\frac{81}{4} = \frac{64}{5}$.

To solve for $\text{X}$, you can set up the equation $\frac{81}{4} = \frac{64}{5} \times \frac{1}{\text{X}}$.

Now, you can solve for $\text{X}$. Cross-multiply again to get $81 \times \text{X} = 64 \times 4 \times 5$.

$81 \times \text{X} = 1280$.

Divide both sides by 81 to solve for $\text{X}$: $\text{X} = \frac{1280}{81}$.
