To find the missing value in the equivalent ratio 12:18 = 16:___, you can use cross-multiplication.
First, you multiply the first term of the first ratio by the second term of the second ratio, and then you set it equal to the product of the second term of the first ratio and the missing value in the second ratio.
So, you get:
12 x ___ = 18 x 16
To solve for the missing value, you can divide both sides of the equation by 12:
___ = (18 x 16)/12
Simplifying the right-hand side, you get:
___ = 24
Therefore, the missing value in the equivalent ratio 12:18 = 16:___ is 24
