Mathematics: ⅓ of the total number of students in a school are in 6th Grade. 1. If “x” stands for the total number of students in the school and “y” stands for the number of 6th Graders, write an equation to represent this situation. 2. How many 6th Graders are there if the school has 90 students? 3. How many 6th Graders are there if the school has 27 students? 4. How many total students are in the school if 42 of them are 6th Graders?

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
