Mathematical Explanation of Equivalent Fractions
Equivalent fractions are fractions that represent the same portion of a whole. For instance, they have the same value but are expressed in different forms. When we talk about the fraction 1/2, it is possible to find other fractions that are equivalent to it.
To determine equivalent fractions of 1/2, we multiply or divide the numerator and the denominator by the same non-zero number. This operation will yield a fraction with the same value as 1/2.
For example:
- Multiplying both the numerator and the denominator of 1/2 by 2 gives us 2/4.
- Multiplying both the numerator and the denominator of 1/2 by 3 gives us 3/6.
- Multiplying both the numerator and the denominator of 1/2 by 4 gives us 4/8.
Thus, 2/4, 3/6, and 4/8 are all equivalent fractions to 1/2 because they represent the same proportion of the whole.
In summary, equivalent fractions are different representations of the same fraction. They can be found by multiplying or dividing the numerator and the denominator of a fraction by the same number.
