To set up a proportion with the fraction \( \frac{30}{54} \), you need to identify another fraction that you want to compare to it. A proportion is an equality of two ratios.
For example, if you wanted to compare \( \frac{30}{54} \) to another fraction \( \frac{x}{y} \), you would write:
\[ \frac{30}{54} = \frac{x}{y} \]
If you have specific values for \( x \) or \( y \) that you want to plug in, you can do so. If you're looking to simplify \( \frac{30}{54} \) first, you would find the greatest common divisor (GCD) of 30 and 54, which is 6:
\[ \frac{30 \div 6}{54 \div 6} = \frac{5}{9} \]
So, \( \frac{30}{54} \) can also be written as \( \frac{5}{9} \). If you have another specific comparison in mind, just let me know!
