Can a percentage be greater than 100%?
Conditions
- The percentage value is strictly greater than 100.
- The denominator remains 100.
Reasoning, step by step
- Rewrite the percentage as a fraction over 100.
- Compare the numerator to the denominator.
- Classify it as an improper fraction if the numerator is larger.
- Conclude the value is greater than 1.
Example
The video shows 126% = and explains that because the top number is bigger than the bottom number, the fraction's value will be greater than one.
Common misconceptions
- Assuming percentages stop at 100%.
- Thinking that a percentage over 100 is mathematically invalid.
