Using proportions, it is found that 12 containers had paint in them.
What is a proportion?
A proportion is a fraction of total amount, and the measures are related using a rule of three.
In this problem, in 1 container she poured 1/8 of a gallon. How many containers are used for 2/3 of a gallon?
The rule of three is:
1 container - 1/8 of a gallon.
x containers - 2/3 of a gallon.
Applying cross multiplication:
\(\frac{1}{8}x = \frac{2}{3}\)
\(2x = 24\)
\(x = 12\)
12 containers had paint in them.
