To find an equivalent ratio of \( 12:36 \) in the form \( x:3 \), you start by simplifying the ratio \( 12:36 \).
-
Divide both terms of the ratio \( 12:36 \) by their greatest common divisor (GCD), which is 12:
\[ \frac{12}{12} : \frac{36}{12} = 1:3 \]
Now you have the simplified ratio \( 1:3 \).
- To express this ratio in the form \( x:3 \), we can see that \( x = 1 \) because the ratio is already in the desired form.
Therefore, the equivalent ratio \( x:3 \) is:
\[ 1:3 \]
Thus, \( x = 1 \).
