How do you create an equivalent fraction?
- Equivalent fractions are two fractions that are written differently but have the same size.
- The two fractions: 1 / 3 and 2 / 6 are equivalent fractions.
- We can multiply the numerator The number on the top of the fraction, above the dividing line of ‘1’ by two to get a new numerator of ‘2’.
How do you make denominators the same when adding fractions?
- To add fractions with the same denominators, the denominator remains the same and we add the numerators together.
- The denominators are the numbers on the bottoms of the fractions and they are the same in both fractions that we are adding.
- The denominators of both fractions are ‘8’ and so the answer will also have a denominator of ‘8’.

Do you need common denominator when adding fractions?
Yes, you need a common denominator when adding fractions. Hopefully, the explanation that follows will give you a better handle on the process: Using 1/2+ 1/3 as an example, 3/3 times 1/2= 3/6 and 2/2 times 1/3= 2/6, then 3/6+ 2/6= 5/6. This is usually explained as “cross multiplication,” where the factors 3/3 and 2/2, which equal 1, are not used.
What is common denominator equivalent?
A common denominator, which means having the same number in the denominator (or the bottom) of each fraction, creates equivalent fractions that can be added, subtracted, or compared.
How do you use the least common denominator with equivalent fractions?
Why is the least common denominator useful?First, find the LCD of the fractions.The least common denominator of 9 and 6 is 18.Next, create equivalent fractions using the LCD as the denominator. To make an equivalent fraction, multiply the numerator and denominator by the same number.Now you can add.
How do you make denominators equivalent?
To make the denominators the same we can: Multiply top and bottom of each fraction by the denominator of the other. We simplified the fraction 2032 to 1016 , then to 58 by dividing the top and bottom by 2 each time, and that is as simple as it can get!
What are the common denominators of 2/3 and 3 4?
23 and 34 are not the same. The two terms can be made the same by finding a common denominator 3x 4 = 12 so 12 will work as a common denominator.
How do you find the common denominator of a fraction?
We can obtain common denominators by multiplying both numerator (top) and denominator (bottom) by the same amount. For example, consider the addition of two fractions that do not have the same denominator: Addition of 2⁄5 and 1⁄2 . First, multiply 2⁄5 by 2⁄2 to get 4⁄10 .
What is the meaning of equivalent fraction?
Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value. For example, 2/4 and 3/6 are equivalent fractions, because they both are equal to the ½. A fraction is a part of a whole.

What are Equivalent Fractions?
Equivalent fractions state that two or more than two fractions are said to be equal if both results are the same fraction after simplification. Let us say, a/b and c/d are two fractions, after the simplification of these fractions, both result in equivalent fractions, say e/f, then they are equal to each other.
How to make the denominator equal to 9?
Multiply 2/3 by 3/3 to make the denominator equal to 9.
Why are fractions the same?
These fractions are actually the same because when we multiply or divide both the numerator and the denominator by the same number, the value of the fraction actually doesn’t change. Therefore, equivalent fractions, when reduced to their simplified value, will all be the same. For example, consider the fraction 1/5.
What happens when two fractions are given?
If two fractions are given, we can simply find their decimals to check if they are equivalent fractions.
Is a fraction equivalent to a decimal?
Since, both the fractions results in the same decimal, thus they are equivalent.
Do denominators have a common multiple?
The answer to this question is that, as the numerator and denominator are not co-prime numbers, therefore they have a common multiple, which on division gives exactly the same value.

Do you always teach the multiply the denominator?
Not always. It depends on my students’ needs but for the most, I do wind up teaching all four ways or addressing them at some point. I have found that a lot of my students are taught the multiply the denominator trick by older siblings. That is the only strategy that I don’t always teach but do address if it comes up.
