We know that

• Each protective coat is 2/27 inches thick.

,

• We need to fill 2/3 inches of this protective coat.

To solve this problem, we need to know the total number of the application needed to fill 2/3 inches. We can form the following expression


(2)/(27)x=(2)/(3)

We solve for x


x=(2\cdot27)/(3\cdot2)=(27)/(3)=9

Therefore, we need 9 applications in total.
