x -----> the number of questions answered correctly
y ----> the total number of questions on a test

For y=40 questions
Find the value of x
substitute

solve for x
Multiply both sides by 40


so
The least number of questions a student can answer correctly is 32
<u><em>Verify the ratio</em></u>
For x=32, y=40

Compare
----> is ok
