How To Find An Equivalent Fraction By Multiplying
Equivalent Fractions
Equivalent fractions can be divers as fractions that may have different numerators and denominators but they represent the same value. For case, 9/12 and vi/8 are equivalent fractions because both are equal to 3/4 when simplified.
All equivalent fractions go reduced to the same fraction in their simplest form as seen in the above example. Explore the given lesson to go a amend idea of how to find equivalent fractions and how to bank check if the given fractions are equivalent.

What are Equivalent Fractions?
Two or more fractions are said to exist equivalent if they are equal to the same fraction when simplified. For example, the equivalent fractions of i/5 are 5/25, half dozen/30, and iv/20, which on simplification, event in the same fraction, that is, 1/five.
Equivalent Fractions Definition
Equivalent fractions are defined as those fractions which are equal to the aforementioned value irrespective of their numerators and denominators. For instance, both vi/12 and four/eight are equal to 1/two, when simplified, which means they are equivalent in nature.
Equivalent Fractions Examples
Here are some examples of equivalent fractions.
Example: 1/two, 2/4, three/6, and 4/8 are equivalent fractions. Let us see how their values are equal. We volition represent each of these fractions as circles with shaded parts. Information technology tin be seen that the shaded parts in all the figures represent the same portion if seen every bit a whole.
Hither, nosotros tin run into that the amount of shaded portion is the same in all the circles. Hence, ane/two, 2/iv, three/6, and four/8 are equivalent fractions.
How to Find Equivalent Fractions?
Equivalent fractions can be written by multiplying or dividing both the numerator and the denominator by the same number. This is the reason why these fractions get reduced to the same number when they are simplified. Permit usa sympathise the two ways in which we can brand equivalent fractions:
- Multiply the numerator and the denominator by the same number.
- Split up the numerator and the denominator by the same number.
Multiply the Numerator and Denominator past the Same Number
To find the equivalent fractions for whatever given fraction, multiply the numerator and the denominator by the same number. For case, to find an equivalent fraction of three/iv, multiply the numerator iii and the denominator iv by the same number, say, 2. Thus, vi/viii is an equivalent fraction of three/4. Nosotros can notice some other equivalent fractions by multiplying the numerator and the denominator of the given fraction past the same number.
- 3/iv= \(\dfrac{3 \times 3}{4 \times 3}\) =9/12
- iii/4=\(\dfrac{iii \times 4}{4 \times 4}\) =12/16
- 3/4=\(\dfrac{3 \times v}{4 \times 5}\) =15/xx
Thus, the equivalent fractions of three/4 are 6/viii, 9/12, 12/16, and 15/xx.
Separate the Numerator and Denominator by the Same Number
To find the equivalent fractions for any given fraction, split the numerator and the denominator by the aforementioned number. For example, to notice an equivalent fraction of 72/108, nosotros will kickoff discover their common factors. We know that two is a common factor of both 72 and 108. Hence, an equivalent fraction of 72/108 can be found by dividing its numerator and denominator by 2. Thus, 36/54 is an equivalent fraction of 72/108. Permit us see how the fraction is further simplified:
- 2 is a common cistron of 36 and 54. Thus, 36/54= \(\dfrac{36 \div 2}{54 \div 2}\)= 18/27
- Once more, 3 is a common factor of 18 and 27. Thus, 18/27= \(\dfrac{18 \div 3}{27 \div three}\)= 6/9
- Again, three is a common factor of vi and 9. Thus, half dozen/9=\(\dfrac{6 \div three}{9 \div 3}\)= ii/3
Therefore, a few equivalent fractions of 72/108 are 36/54, 18/27, half dozen/9, and 2/3. Here, 2/3 is the simplified form of 72/108 as in that location is no common cistron (other than i) of 2 and 3.
How to Make up one's mind if Two Fractions are Equivalent?
We need to simplify the given fractions to observe whether they are equivalent or not. Simplification to get equivalent numbers tin be washed to a point where both the numerator and denominator should still be whole numbers. There are various methods to identify if the given fractions are equivalent. Some of them are:
- Making the denominators the same.
- Finding the decimal course of both the fractions.
- Cross multiplication method.
- Visual method.
Let u.s.a. identify whether 2/half-dozen and 3/nine are equivalent fractions by each of these methods.
Making the Denominators the Same
The denominators of the fractions, 2/half-dozen and 3/9 are 6 and ix. The Least Common Multiple (LCM) of the denominators 6 and 9 is 18. Permit united states of america make the denominators of both fractions 18, by multiplying them with suitable numbers.
- 2/6=\(\dfrac{2 \times 3}{6 \times 3}\)= 6/18
- 3/9=\(\dfrac{3 \times 2}{9 \times two}\)= 6/18
We can observe that both the fractions are equivalent to the same fraction six/eighteen. Thus, the given fractions are equivalent.
Note: If the fractions are Non equivalent, we can check the greater or smaller fraction by looking at the numerator of both the resultant fractions. Hence, this method tin as well be used for comparing fractions.
Finding the Decimal form of Both the Fractions
Permit united states of america discover the decimal course of both the fractions ii/6 and 3/9 to run into if they requite the same value.
- two/6= 0.3333333...
- 3/9= 0.3333333...
The decimal values of both the fractions are the same and hence, they are equivalent.
Cross Multiplication Method
To identify whether 2/6 and 3/9 are equivalent, we cross multiply them. If both the products are the same, the fractions are equivalent.
Since both the products here are 18, the given fractions are equivalent.
Visual Method
Allow us represent each of the fractions ii/6 and 3/9 pictorially on identical shapes and check if the shaded portions of both are equal.
Nosotros tin see that the shaded portions of both the circles depict the same value. In other words, information technology can be seen that the shaded parts in both the figures represent the same portion if seen as a whole. Hence, the given fractions are equivalent.
Equivalent Fractions Chart
Charts and tables are often used to represent concepts in a amend manner since they serve as a handy reference for calculations and are easier to understand. Ballast charts and tables, like the one given beneath, brand it easier for the students to sympathise equivalent fractions. Let us use the post-obit chart to find the equivalent fractions of 1/4.
From this nautical chart, we tin observe that the equivalent fractions of i/4 are: two/8, 3/12, four/16,...
Tips on Equivalent Fractions
- Two fractions are said to be equivalent if their values (decimal/graphical) are the same.
- We normally multiply the numerator and denominator of a fraction by the same number to go its equivalent fraction.
- The 'Cross multiplication method' is used to determine whether any two fractions are equivalent or non.
- 'Making the denominators the aforementioned' is another method used to decide if ii or more fractions are equivalent.
