ms quarles gave a math unit test to each of her four classes. ms quarles grades 25 percent of the tests, which is 30 papers. how many students does she have in each class
AAAaannndd the bot gets it wrong yet again!
.25x = 30
x = 120
x/4 = 30
To determine the total number of students in each class, we can set up a proportion using the given information.
Let's start by assuming the number of students in each class is "x."
According to the question, Ms. Quarles grades 25 percent of the tests, which is 30 papers.
So, we can set up the proportion:
25/100 = 30/x
To solve for x, we can cross-multiply and solve the equation:
25x = 30 * 100
25x = 3000
x = 3000/25
Evaluating this expression, we find that x = 120.
Therefore, each class has 120 students.
To find out how many students Ms. Quarles has in each class, we need to use the information provided.
We know that Ms. Quarles graded 25 percent of the tests, which is 30 papers. This means that 30 papers represent 25 percent of the total number of papers graded.
To find the total number of papers, we can set up a proportion:
25/100 = 30/x
We know that 25 percent is equivalent to 0.25 (since 25 divided by 100 is 0.25).
0.25 = 30/x
Now, we can solve for 'x' by multiplying both sides of the equation by 'x' to isolate it:
0.25x = 30
To get 'x' alone, divide both sides of the equation by 0.25:
x = 30/0.25
Performing the calculation, we find:
x = 120
Therefore, Ms. Quarles has 120 students in each class.
