Write the ratio 12:36 as an equivalent ratio of x:3

To find the equivalent ratio of 12:36 in the form of \( x:3 \), you can set up the proportion:

\[ \frac{12}{36} = \frac{x}{3} \]

To solve for \( x \), you can cross-multiply:

\[ 12 \cdot 3 = 36 \cdot x \]

This simplifies to:

\[ 36 = 36x \]

Now, divide both sides by 36:

\[ x = \frac{36}{36} = 1 \]

Thus, the equivalent ratio is \( 1:3 \).
