Fractions Concepts Test Review

Front

What is a fraction?

Back

A fraction represents a part of a whole and is written as 'a/b', where 'a' is the numerator (the number of parts) and 'b' is the denominator (the total number of equal parts).

Front

What does it mean for two fractions to be equivalent?

Back

Two fractions are equivalent if they represent the same value or proportion, even if they have different numerators and denominators.

Front

How do you find the least common denominator (LCD) of two fractions?

Back

The least common denominator is the smallest multiple that both denominators share. To find it, list the multiples of each denominator and identify the smallest common multiple.

Front

What is the process to reduce a fraction to its lowest terms?

Back

To reduce a fraction, divide both the numerator and the denominator by their greatest common factor (GCF).

Front

How do you add fractions with different denominators?

Back

To add fractions with different denominators, first find the least common denominator, convert each fraction to an equivalent fraction with that denominator, and then add the numerators.

Front

What is the difference between a proper fraction and an improper fraction?

Back

A proper fraction has a numerator smaller than its denominator (e.g., 3/4), while an improper fraction has a numerator that is equal to or larger than its denominator (e.g., 5/4).

Front

How do you convert an improper fraction to a mixed number?

Back

To convert an improper fraction to a mixed number, divide the numerator by the denominator. The quotient becomes the whole number, and the remainder becomes the new numerator over the original denominator.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a proper fraction (e.g., 2 1/3).

Front

How do you subtract fractions?

Back

To subtract fractions, ensure they have the same denominator. If not, find the least common denominator, convert the fractions, and then subtract the numerators.

Front

What is the significance of the numerator in a fraction?

Back

The numerator indicates how many parts of the whole are being considered.
