18 students are 1/10 of the number of seventh graders [tex]s[/tex]

[tex]18 = 0.1 s[/tex]

First choice.

Answer:

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 [tex]\frac{1}{10}[/tex] of s = 18

(0.1)s = 18

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