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

How do you subtract fractions with like denominators?

Back

To subtract fractions with like denominators, 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, 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.

Front

What is the least common denominator (LCD)?

Back

The least common denominator is the smallest number that can be used as a common denominator for two or more fractions. It helps in adding or subtracting fractions.

Front

How do you find the least common multiple (LCM) of two numbers?

Back

To find the least common multiple, list the multiples of each number and find the smallest multiple they have in common. For example, the LCM of 3 and 4 is 12.

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 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 the process of simplifying a fraction?

Back

Simplifying a fraction means reducing it to its simplest form by dividing the numerator and denominator by their greatest common factor (GCF). For example, 4/8 simplifies to 1/2.
