What are the rules of equivalent fractions?
Equivalent Fractions Rule. A rule stating that if the numerator and denominator of a fraction are multiplied by the same nonzero number, the result is a fraction that is equivalent to the original fraction. This rule can be represented as: a//b = (n * a)//(n * b).
How to make an equivalent fraction?
It is possible by these methods:
- Method 1: Make the Denominators the same

How to solve equivalent fractions?
Methods to Determine Equivalent Fractions
- Method 1: By making the denominators the same, we can evaluate if two fractions are equivalent. For example, find if 2/3 and 6/9 are equivalent.
- Method 2: Since, both the values are equal, therefore, 1/2 and 3/6 are equivalent fractions.
- Method 3: If two fractions are given, we can simply find their decimals to check if they are equivalent fractions.
How to see if fractions are equivalent?
- Equivalent fractions may look different, but they have the same value.
- You can multiply or divide to find an equivalent fraction.
- Adding or subtracting does not work for finding an equivalent fraction.
- If you multiply or divide by the top of the fraction, you must do the same to the bottom.

What are Equivalent Fractions?
Equivalent fractions are fractions with different numbers representing the same part of a whole. They have different numerators and denominators, but their fractional values are the same.
How to make a fraction equivalent?
Multiply both the numerator and denominator of a fraction by the same whole number. As long as you multiply both top and bottom of the fraction by the same number, you won’t change the value of the fraction , and you’ll create an equivalent fraction.
What is half of a fraction?
For example, think about the fraction 1/2. It means half of something. You can also say that 6/12 is half, and that 50/100 is half. They represent the same part of the whole. These equivalent fractions contain different numbers but they mean the same thing: 1/2 = 6/12 = 50/100
What is 2/5 as a decimal?
That’s literally all there is to it! 2/5 as a decimal is 0.4.
Why would you want to convert 2/5 to a decimal?
This is a great question. We have lots of calculations on this site about converting a fraction into a decimal but why would you want or need to do that in the first place?
Is it easier to understand fractions or decimals?
In real life, we mostly deal with decimals (like currency, for example) and since our brains are taught from a young age to understand and compare decimals more often than they are fractions, it’s easier to understand and compare fractions if they are converted to a decimal first!
How to Calculate 2.5 as a Fraction?
For calculation, here’s how to convert 2.5 as a Fraction using the formula above, step by step instructions are given below
What is 2.5 decimal?
2.5 Decimal is equal to 2 1 / 2 or 5 / 2 as a Fraction.
How to find equivalent fractions?

Can you convert fractions to decimals?
This Equivalent Fractions Table/Chart contains common practical fractions. You can easily convert from fraction to decimal, as well as, from fractions of inches to millimeters.
How to convert decimals to fractions?
It does however require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 10 1, the second 10 2, the third 10 3, and so on. Simply determine what power of 10 the decimal extends to , use that power of 10 as the denominator, enter each number to the right of the decimal point as the numerator, and simplify. For example, looking at the number 0.1234, the number 4 is in the fourth decimal place which constitutes 10 4, or 10,000. This would make the fraction#N#1234#N##N#10000#N#, which simplifies to#N#617#N##N#5000#N#, since the greatest common factor between the numerator and denominator is 2.
What is fraction in math?
In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction. 3.
How to multiply fractions?
Just multiply the numerators and denominators of each fraction in the problem by the product of the denominators of all the other fractions (not including its own respective denominator) in the problem.
How to find common denominator of fractions?
One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. The numerators also need to be multiplied by the appropriate factors to preserve the value of the fraction as a whole. This is arguably the simplest way to ensure that the fractions have a common denominator. However, in most cases, the solutions to these equations will not appear in simplified form (the provided calculator computes the simplification automatically). Below is an example using this method.
How to divide fractions?
In order to divide fractions, the fraction in the numerator is multiplied by the reciprocal of the fraction in the denominator. The reciprocal of a number a is simply. . When a is a fraction, this essentially involves exchanging the position of the numerator and the denominator. The reciprocal of the fraction.
What is fraction used for in engineering?
In engineering, fractions are widely used to describe the size of components such as pipes and bolts. The most common fractional and decimal equivalents are listed below.
Is it easier to work with simplified fractions?
It is often easier to work with simplified fractions. As such, fraction solutions are commonly expressed in their simplified forms.#N#220#N##N#440#N#for example, is more cumbersome than#N#1#N##N#2#N#. The calculator provided returns fraction inputs in both improper fraction form, as well as mixed number form. In both cases, fractions are presented in their lowest forms by dividing both numerator and denominator by their greatest common factor.
