5th Grade Multiplying Fractions

Front

What is a fraction?

Back

A fraction represents a part of a whole and is expressed as a ratio of two integers, with a numerator (top number) and a denominator (bottom number).

Front

How do you multiply a fraction by a whole number?

Back

To multiply a fraction by a whole number, multiply the numerator of the fraction by the whole number and keep the denominator the same. For example, \( \frac{1}{3} \times 5 = \frac{1 \times 5}{3} = \frac{5}{3} \).

Front

What is the product of two fractions?

Back

The product of two fractions is found by multiplying the numerators together and the denominators together. For example, \( \frac{1}{2} \times \frac{1}{4} = \frac{1 \times 1}{2 \times 4} = \frac{1}{8} \).

Front

What is the simplified form of \( \frac{2}{20} \)?

Back

The simplified form of \( \frac{2}{20} \) is \( \frac{1}{10} \) because both the numerator and denominator can be divided by 2.

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 becomes the whole number, and the remainder becomes the new numerator over the original denominator.

Front

What does the denominator of a fraction represent?

Back

The denominator of a fraction represents the total number of equal parts into which the whole is divided.

Front

What does the numerator of a fraction represent?

Back

The numerator of a fraction represents the number of parts being considered out of the total parts represented by the denominator.

Front

How do you find a common denominator for two fractions?

Back

To find a common denominator for two fractions, identify the least common multiple (LCM) of the two denominators.

Front

What is the relationship between fractions and division?

Back

Fractions can be interpreted as division; for example, \( \frac{a}{b} \) can be read as 'a divided by b'.

Front

What is a proper fraction?

Back

A proper fraction is a fraction where the numerator is less than the denominator, such as \( \frac{1}{3} \).
