What is a fraction?

Back

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 it mean to add fractions with like denominators?

Back

Adding fractions with like denominators means you keep the denominator the same and add the numerators. For example, 1/4 + 2/4 = (1+2)/4 = 3/4.

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, which means 2 whole parts and 1/3 of another part.

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 new numerator over the original denominator. For example, 7/4 = 1 3/4.

Front

What is the least common denominator (LCD)?

Back

The least common denominator is the smallest number that can be a common denominator for two or more fractions. For example, the LCD of 1/3 and 1/4 is 12.

Front

How do you subtract fractions with unlike denominators?

Back

To subtract fractions with unlike denominators, first find the least common denominator, convert the fractions to equivalent fractions with that denominator, and then subtract the numerators.

Front

What is a reciprocal?

Back

A reciprocal of a fraction is obtained by flipping the numerator and denominator. For example, the reciprocal of 3/4 is 4/3.

Front

How do you multiply fractions?

Back

To multiply fractions, multiply the numerators together and the denominators together. For example, (2/3) * (3/4) = (2*3)/(3*4) = 6/12, which simplifies to 1/2.

Front

What is a benchmark fraction?

Back

A benchmark fraction is a commonly used fraction that helps to estimate or compare other fractions. Examples include 1/2, 1/4, and 3/4.

Front

How do you compare two fractions?

Back

To compare two fractions, you can find a common denominator or convert them to decimals. The fraction with the larger numerator (after finding a common denominator) is greater.
