In a school 5/8 of the students are girls. If there are 135 boys, what is the total number of students at the school?
3/8 x = 135

To find the total number of students at the school, we need to determine the number of girls and then add them to the number of boys.
Given that 5/8 of the students are girls, we can assume that 5/8 of the total number of students represents the number of girls. Let's denote the total number of students as "x".
So, the number of girls is (5/8) * x.
We are also informed that there are 135 boys. Therefore, the number of boys is 135.
To solve for "x", we can set up an equation:
(5/8) * x + 135 = x
To solve this equation, let's first multiply both sides by 8 to eliminate the fraction:
8 * (5/8) * x + 8 * 135 = 8 * x
Simplifying the equation:
5x + 1080 = 8x
Subtracting 5x from both sides:
1080 = 3x
Now, divide both sides by 3:
1080/3 = x
x = 360
Therefore, the total number of students at the school is 360.
(3/8)x = 135
x = ?
