Question

2/7 Of the students in the school or in sixth grade. C] If the school has X students write an expression for the number of sixth graders in terms of X.

Answer 1

The expression for the number of sixth graders in terms of x is
`n = (2x)/(7)`

Solution:

Given that ,
`(2)/(7)` of the students in school are in sixth grade

To find: Expression for number of sixth graders

Let the total number of students in school be "x"

From given statement,

`(2)/(7)` of the students in school are in sixth grade

Which means,
`(2)/(7)` of total number of students are in sixth grade

Let "n" be the number of students in sixth grade

Then by given statement,

n =
`(2)/(7)` of total number of students

`n = (2)/(7) \text{ of } x\\\\n = (2)/(7) * x\\\\n = (2x)/(7)`

Thus the expression in terms of x is found
