Express the statement in the form of a percentage: "In a class of 45,36 students passed."

Answer

To express the statement "In a class of 45, 36 students passed" in the form of a percentage, we can follow these steps:

### Step 1: Identify the total number of students and the number of students who passed.
- Total number of students = 45
- Number of students who passed = 36

### Step 2: Set up the fraction to find the percentage.
- We need to find what percentage 36 is of 45. This can be expressed as:
\[ \text{Percentage} = \left(\frac{\text{Number of students who passed}}{\text{Total number of students}}\right) \times 100 \]
- Substituting the values:
\[ \text{Percentage} = \left(\frac{36}{45}\right) \times 100 \]

### Step 3: Simplify the fraction.
- To simplify \(\frac{36}{45}\), we can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 9.
\[ \frac{36 \div 9}{45 \div 9} = \frac{4}{5} \]

### Step 4: Convert the simplified fraction to a percentage.
- Now we can calculate the percentage:
\[ \text{Percentage} = \left(\frac{4}{5}\right) \times 100 \]

### Step 5: Perform the multiplication.
- To perform the multiplication:
\[ \frac{4 \times 100}{5} = \frac{400}{5} = 80 \]

### Conclusion:
- Therefore, the percentage of students who passed is:
\[ 80\% \]
