To determine which of the given ratios is equivalent to \( \frac{3}{2} \), we can simplify or compare each option:
-
\( \frac{9}{6} \): \[ \frac{9}{6} = \frac{9 \div 3}{6 \div 3} = \frac{3}{2} \] This is equivalent to \( \frac{3}{2} \).
-
1: \[ 1 = \frac{2}{2} \] This is not equivalent to \( \frac{3}{2} \).
-
\( \frac{9}{4} \): This cannot be simplified to \( \frac{3}{2} \) since: \[ \frac{9}{4} \neq \frac{3}{2} \]
-
\( \frac{2}{3} \): This cannot be simplified to \( \frac{3}{2} \) since: \[ \frac{2}{3} \neq \frac{3}{2} \]
From the analysis, the ratio that is equivalent to \( \frac{3}{2} \) is \( \frac{9}{6} \).
