Answer 2

Option (A) 18 = 0.1s

Step-by-step explanation:

Every seventh-grade student at Martin Middle School takes one world language class.

Now we will form the equation as per statement of the question.

Let total students of seventh-grade = s

" one tenth of seventh grade students take French."

" Students who took French were 18."

So of s = 18

(0.1)s = 18

therefore, Option (A) 18 = 0.1s is the answer.
