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 $n = \frac{2x}{7}$

Solution:

Given that , $\frac{2}{7}$ 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,

$\frac{2}{7}$ of the students in school are in sixth grade

Which means, $\frac{2}{7}$ of total number of students are in sixth grade

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

Then by given statement,

n = $\frac{2}{7}$ of total number of students

$n = \frac{2}{7} \text{ of } x\\\\n = \frac{2}{7} \times x\\\\n = \frac{2x}{7}$

Thus the expression in terms of x is found
