Which of the following are features or uses of an improper fraction?Select all that applyNumerator GREATER than the denominatorUsed to easily estimate the scale of the fractionType of rational numberNumerator SMALLER than the denominatorAre easier to use in calculations than mixed numbers areMust be of a value larger than 1

The features or uses of an improper fraction are:

1. Numerator GREATER than the denominator: This is a defining characteristic of an improper fraction. The numerator (top number) is always larger than the denominator (bottom number).

2. Type of rational number: Yes, an improper fraction is a type of rational number. Rational numbers are numbers that can be expressed as a fraction where both the numerator and denominator are integers and the denominator is not zero.

3. Are easier to use in calculations than mixed numbers are: This can be subjective and depends on the specific calculation. However, in many cases, it is easier to perform multiplication or division with improper fractions than with mixed numbers.

4. Must be of a value larger than 1: Yes, since the numerator is larger than the denominator, the value of an improper fraction is always greater than 1.

The following are NOT features or uses of an improper fraction:

1. Used to easily estimate the scale of the fraction: The scale of a fraction is not necessarily easier to estimate if it is an improper fraction. This would depend on the specific numbers involved.

2. Numerator SMALLER than the denominator: This is not a feature of an improper fraction. If the numerator is smaller than the denominator, the fraction is a proper fraction, not an improper fraction.
