Equivalent Fractions – Definition

In this learning text we will be looking at equivalent fractions and how to find equivalent fractions. You may already know from our previous videos what a fraction is. Let’s look at the recap of the definition of what fractions and equivalent fractions are.

  • Fractions always represent a part of a whole. For example, if a pizza is divided into four equal pieces, one piece is called $\frac{1}{4}$ of a whole pizza.

  • Equivalent fractions are fractions which have the same value but are represented with a different numerator and denominator.

Equivalent fractions are created by breaking a whole into smaller equal parts. For example, the equivalent fractions visual diagram below is showing a whole as a fraction of $\frac{2}{2}$ and another fraction which is still one whole as a fraction $\frac{8}{8}$. So, the fractions $\frac{2}{2}$ and $\frac{8}{8}$ are equivalent fractions.

To create equivalent fractions, we can increase the number of pieces by multiplying the numerator and the denominator by the same n factor.

In mathematics, we use a multiplication expression to represent an equivalent fraction. The left-hand side of the expression represents our fraction and the right-hand side of the expression represents an equivalent fraction multiplied by n, where n represents any number. The equal sign shows that both sides of the expression are equal to each other. The bigger the number we multiply the fraction by, the more equal parts the whole has.

Now, we can look at some examples for better understanding of equivalent fractions and after that you can practice equivalent fractions worksheet 4th grade or play equivalent fractions bingo.

Equivalent Fractions – Example 1

Let’s look at our first fraction, which is $\frac{1}{2}$. If we multiply the numerator and the denominator by two, we have generated an equivalent fraction which is $\frac{2}{4}$. The size of these parts is different, but the size of the whole remains the same.

Equivalent Fractions – Example 2

In our second example, we are looking at $\frac{3}{4}$. Let’s multiply the numerator and the denominator of the fraction by three, so we will get $\frac{9}{12}$. In this example, the n equals three.

We can also use a different factor; this time let’s multiply the numerator and the denominator of $\frac{3}{4}$by six, so we will get an equivalent fraction which is $\frac{18}{24}$. This time, the n factor equals six.

We can changethen factor for any other number, we just must remember to multiply the numerator and the denominator by the same n factor.

Equivalent Fractions – Summary

How do we generate or create an equivalent fraction? Look at the summary below:

  • Equivalent fractions are fractions that have the same value but have different numbers in the numerators and denominators.
  • Equivalent fractions are created by breaking a whole into smaller equal parts and having a greater number of pieces.
  • We can increase the number of parts in a fraction by multiplying the numerator and the denominator by the same factor.
  • Use the multiplication expression.
  • Pick a number and then multiplying the numerator and denominator by the chosen factor.

Transcript Generate Equivalent Fractions

“B(....) TWO-THIRDS!” It’s fraction night down at the bingo hall and Axel and Tank are excited to try to win the night’s top prize… which is a trip for two to Submersive Studios! In order to be the first to fill their bingo card, they need to find… Equivalent Fractions. Equivalent fractions are fractions that have the same value but have different numbers in the numerators and denominators. They are created by breaking the whole into smaller parts and having a greater number of pieces. We increase the number of parts in the fraction by multiplying the numerator and denominator by the same factor. Mathematically, we can show how to generate, or create, equivalent fractions through a multiplication expression. In this formula, the over represents our fraction. We use the to stand for the NUMBER we are going to multiply both the numerator and denominator by. The equal sign shows the two sides of this expression are equivalent. One-half and two-fourths are an example of equivalent fractions. In one half, the whole is divided into two larger parts and one of the halves is shaded in. To make two-fourths, we would multiply the numerator and denominator by two. Two times two equals four(…)so the whole is now grouped into four parts… and one times two equals two, so there are now two parts shaded in. We could continue generating fractions equal to one-half by multiplying the numerator and denominator by other factors. The size of these parts differs, but the size of the whole remains the SAME(…)and therefore so does the value of the fraction. The next fraction called out is three-fourths. To find an equivalent fraction on his card, Axel is going to multiply the numerator and denominator by three. In the denominator, we have four times three, which makes twelve... Nine-twelfths is equivalent to three-fourths. Tank decides to multiply the fraction by sixs. Four times six equals twenty-four and three times six is eighteen. Three-fourths is also equivalent to eighteen twenty-fourths. Five-sixths is the next fraction called. Axel is going to make an equivalent fraction by multiplying the numerator and denominator by five. What is the equivalent fraction? Twenty-five thirtieths. Tank decides to multiply the numerator and denominator by eight. What equivalent fraction did he make? Forty, forty-eighths. These aren’t the only fractions that would be equivalent. In the comment section, share other fractions that are also equivalent to five-sixths and what you multiplied the numerator and denominator by it to make them. “G (...) FOUR-FIFTHS” While Axel and Tank look for an equivalent fraction on their card, let’s review. Remember… Equivalent fractions are fractions that have the same value but have different numbers in the numerators and denominators. They are created by breaking the whole into smaller parts and having a greater number of pieces. We increase the number of parts in the fraction by multiplying the numerator and denominator by the same factor. Mathematically, we can show how to generate, or create, equivalent fractions through a multiplication expression. "Woooooooah! I THINK I HAVE IT!" [Woman's voice] "BINGO!" "GRANDMA?!"
