A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, 1/2 means one part out of two equal parts.

Front

What does the numerator in a fraction represent?

Back

The numerator is the top number of a fraction and represents how many parts we have.

Front

What does the denominator in a fraction represent?

Back

The denominator is the bottom number of a fraction and represents the total number of equal parts in the whole.

Front

How do you add fractions with the same denominator?

Back

To add fractions with the same denominator, keep the denominator the same and add the numerators. For example, 1/4 + 2/4 = (1+2)/4 = 3/4.

Front

How do you add fractions with different denominators?

Back

To add fractions with different denominators, first find a common denominator, convert the fractions, and then add the numerators.

Front

What is the process to subtract fractions?

Back

To subtract fractions, if they have the same denominator, subtract the numerators and keep the denominator the same. If they have different denominators, find a common denominator first.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction. For example, 1 1/2 is a mixed number.

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 is the whole number, and the remainder is the new numerator.

Front

What is the fraction of a set?

Back

The fraction of a set is the part of the total that is represented by the fraction. For example, if there are 10 apples and 3 are red, the fraction of red apples is 3/10.

Front

How do you find the fraction of a group?

Back

To find the fraction of a group, divide the number of items in the subgroup by the total number of items in the group.
