To solve this problem:

1. The student scored 80% on the test.
2. The test had 40 questions.

We can find the number of correct answers first and then subtract from the total to find how many were missed.

### Step 1: Calculate the number of correct answers
The student answered 80% of the questions correctly. 
To find the number of correct answers:
\[
\text{Correct answers} = 80\% \times 40 = 0.80 \times 40 = 32
\]

### Step 2: Calculate the number of missed questions
The total number of questions was 40, so the number of missed questions is:
\[
\text{Missed questions} = 40 - 32 = 8
\]

Thus, the student missed **8 questions**.

Here are some related questions to expand your understanding:
1. If the test had 50 questions and the student earned 90%, how many questions were missed?
2. How would the student's score change if they missed 10 questions instead of 8?
3. If another student earned 70% on a 40-question test, how many did they miss?
4. How do percentages relate to fractions and decimals in calculating test scores?
5. How can you quickly calculate missed questions given any percentage?

**Tip:** When dealing with percentages, converting them into decimals (by dividing by 100) often simplifies calculations.

A student earned a grade of 80% on a test. If the test had 40 questions, how many questions did the student miss?

Determine how many questions a student missed when they scored 80% on a 40-question test. This problem involves understanding percentages and basic arithmetic operations, making it suitable for students in Grades 5-7.
