Answer:
s = 6
Step-by-step explanation:
In order to determine the value of s divide the coefficient on both sides.
In simpler terms, a coefficient is a number attached to the variable, which in this case must be divided to remove the coefficient and determine s.
72/12 = 6
Answer: s = 6

x = 8(0.25) . . . . multiply by 8
x = 2
_____
<em>Additional comment</em>
I like to write proportions with the variable in the numerator. That way they are easily solved by a single multiplication. The trick is to get corresponding parts in the same positions. Here, the fractions are written ...
B/A = smaller part / larger part = x/8 = 0.25/1
