Write a proportion to find how many points x a student needs to score on a test worth 50 points to get a test score of 40%.
To find how many points x a student needs to score on a test worth 50 points to get a test score of 40%, we can set up a proportion:
x/50 = 40/100
To solve for x, you can cross-multiply:
100x = 40 * 50
Now, you can solve for x by dividing both sides of the equation by 100:
x = (40 * 50) / 100
Simplifying the equation further:
x = 2000 / 100
x = 20
Therefore, the student needs to score 20 points on the test worth 50 points in order to achieve a test score of 40%.
