There are 50% Hispanics and 30% black people in a school and there a 2% white people in a school. How many white
People are there?

Answer:

It depends on the number of students in that school.

For example in a school of 200,000 students there would be 100,000 Hispanic students, 60,000 black students and 40,000 white students.

Meanwhile a school with only 10,000 students will have 5,000 Hispanic students, 3,000 black students and a small population of 2,000 white students.

The way percents work is by a scale that stops at 100%, meaning you can't have anything higher than 100%, like 200% or 300%, despite some people's wishes. Since 50% is half of 100%, and we are referring to the entire school's population, you would take half of the school's population and that would be 50% of it. Another helpful thing to consider, if the number ends in all zeros like 200,000 and 10,000, the number you're looking for is going to be the same as its percent. Like how in the second example, 20% of 10,000 is 2,000.

I hope this makes sense
