Brown 5.NF.1 - 5.NF.3

Front

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 add fractions with unlike denominators?

Back

To add fractions with unlike denominators, you first find a common denominator, convert the fractions, and then add the numerators. For example, 1/3 + 1/4 becomes 4/12 + 3/12 = 7/12.

Front

What is a mixed number?

Back

A mixed number is a whole number combined with a fraction. For example, 2 1/2 means 2 whole parts and 1/2 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 over the original denominator is the fraction. For example, 7/4 = 1 3/4.

Front

What is the process of subtracting fractions?

Back

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

Front

What is a common denominator?

Back

A common denominator is a shared multiple of the denominators of two or more fractions. It allows you to add or subtract fractions easily.

Front

What does it mean to simplify a fraction?

Back

Simplifying a fraction means reducing it to its simplest form, where the numerator and denominator have no common factors other than 1. For example, 4/8 simplifies to 1/2.

Front

What is the least common multiple (LCM)?

Back

The least common multiple (LCM) is the smallest multiple that two or more numbers share. It is often used to find a common denominator.

Front

How do you multiply fractions?

Back

To multiply fractions, multiply the numerators together and the denominators together. For example, 1/2 * 3/4 = (1*3)/(2*4) = 3/8.
