To solve for the missing value represented by the question mark in the equation \( \frac{3}{11} = \frac{9}{?} \), you can set up a proportion.
Given:
\[ \frac{3}{11} = \frac{9}{x} \]
To find \( x \), solve the proportion by cross-multiplying:
\[ 3x = 11 \times 9 \]
\[ 3x = 99 \]
Now, divide both sides by 3:
\[ x = \frac{99}{3} \]
\[ x = 33 \]
So, the missing value is \( 33 \). Therefore,
\[ \frac{3}{11} = \frac{9}{33} \]
3/11 = 9/?
