Which of the following is true about a fraction whose numerator is greater than its denominator?

A fraction whose numerator is greater than its denominator is defined as an improper fraction. In this type of fraction, the value is greater than one because the amount in the numerator exceeds the amount in the denominator. This means that it represents a quantity that can be converted into a whole number plus a proper fraction.

For example, the fraction 7/5 has a numerator of 7, which is greater than the denominator of 5, indicating that it is an improper fraction. Improper fractions can also be converted into mixed numbers, which are a combination of whole numbers and fractions, but the definition specifically pertains to the relationship between the numerator and denominator.

The other options are not applicable in this context. A proper fraction has a numerator that is less than its denominator, so it cannot be considered here. A mixed number represents a whole number and a proper fraction combined, which doesn't directly describe the scenario where the numerator is greater. Lastly, a decimal is a different representation of numbers that is not limited to the structure of fractions. Thus, the statement about the improper fraction is the most accurate.
