3/11 = 9/?

1 answer

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,

\[ \frac{3}{11} = \frac{9}{33} \]
