What does the numerator in a fraction represent?

Back

The numerator is the top number in a fraction. It represents how many parts we have.

Front

What does the denominator in a fraction represent?

Back

The denominator is the bottom number in a fraction. It shows how many equal parts the whole is divided into.

Front

What is an equivalent fraction?

Back

Equivalent fractions are different fractions that represent the same value. For example, 1/2 and 2/4 are equivalent fractions.

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 subtract fractions with the same denominator?

Back

To subtract fractions with the same denominator, keep the denominator the same and subtract the numerators. For example, 3/5 - 1/5 = (3-1)/5 = 2/5.

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 becomes the numerator of the fraction.
