What is a fraction?

What does the numerator in a fraction represent?

Back

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

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

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, 2 1/3 is a mixed number, where 2 is the whole number and 1/3 is the fraction.

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. For example, 7/4 = 1 3/4.

Front

What is equivalent fractions?

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 find equivalent fractions?

Back

To find equivalent fractions, multiply or divide the numerator and denominator of a fraction by the same number. For example, for 1/3, multiplying both by 2 gives 2/6.

Front

What is the simplest form of a fraction?

Back

The simplest form of a fraction is when the numerator and denominator have no common factors other than 1. For example, 4/8 can be simplified to 1/2.
