What Are Equivalent Fractions?
Equivalent fractions are fractions that name the same amount
Learning Objective
Students will learn that equivalent fractions can look different but still show the same amount, and that multiplying or dividing the top and bottom by the same number keeps the value the same.
What You'll Learn
- Fraction bars, circles, and number lines can show when fractions are equal
- One-half, two-fourths, and four-eighths can all be the same size
- If you multiply the numerator and denominator by the same number, the fraction stays equal
- If you divide the numerator and denominator by the same number, you can make an equivalent fraction in simpler form
- Equivalent fractions only work when you are talking about equal-size wholes
Words to Know
- Equivalent fractions
- Fractions that look different but mean the same amount
- "1/2 and 2/4 are equivalent fractions."
- Numerator
- The top number in a fraction
- "In 3/4, the 3 is the numerator."
- Denominator
- The bottom number in a fraction
- "In 3/4, the 4 is the denominator."
- Fraction bar
- A model split into equal parts to show a fraction
- "The fraction bar showed that 2/4 is the same as 1/2."
- Whole
- One complete shape or object before it is split
- "We used the same whole pizza to compare the fractions."

Fun Facts
Equivalent fractions are fractions that name the same point on a number line and the same amount of a whole.

A fraction like 1/2 is equal to 2/4 and 4/8 because the same whole is split into more equal parts, but the same amount is shaded.
