Question

⅓ of the total number of students in a school are in 6th Grade.

Answer 1

Step-by-step explanation:

1. 'x' is the total no. of students and 'y' is no. of 6th graders.

1/3 of the total students are 6th graders.

So the equation will be

1/3 × x = y

x/3 = y

2. If x = 90

y = 90/3

y = 30

3. If x = 27,

y = 27/3

y = 9

4. If y = 42

x/3 = 42

x = 42 x 3

x = 126
