An improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number).
Let's analyze each option:
-
2025: This is a whole number, not a fraction.
-
Start Fraction 20 over 25 End Fraction: This simplifies to \( \frac{20}{25} = \frac{4}{5} \), which is not an improper fraction (the numerator is less than the denominator).
-
729: This is also a whole number, not a fraction.
-
Start Fraction 25 over 20 End Fraction: This simplifies to \( \frac{25}{20} = \frac{5}{4} \), which is an improper fraction (the numerator is greater than the denominator).
-
297: This is again a whole number, not a fraction.
-
Start Fraction 9 over 7 End Fraction: This fraction is \( \frac{9}{7} \), which is also an improper fraction (the numerator is greater than the denominator).
Based on this analysis, the options that represent improper fractions are:
- Start Fraction 25 over 20 End Fraction (Option 3)
- Start Fraction 9 over 7 End Fraction
If you can select only one, the most straightforward improper fraction option is Start Fraction 25 over 20 End Fraction.
