in a survey 15% of the student said they don't own computers if 75 didn't own computers how many took the survey

Equation:

.15x = 75

Solve for x.

To find out how many students took the survey, we can use the fact that 15% of the students said they don't own computers. We know that 75 students didn't own computers, so we need to find what percentage of the total number of students this represents.

Let's assume the total number of students who took the survey is represented by "x".

15% of x can be calculated by multiplying x by 0.15.

Therefore, 0.15x = 75.

To solve for x, we divide both sides of the equation by 0.15:

x = 75 / 0.15

By dividing 75 by 0.15, we find that x is equal to 500.

Hence, 500 students took the survey.
