Equivalent fractions

Equivalent Fractions

Equivalent fractions means that the area or fractional part that we are talking about are the same but one might have more parts. 

For example: 

1/2     and      2/4 are equivalent meaning the area that is shaded is the same size but in the fraction on the bottom it has been divided into more parts.





To find equivalent fractions:

We can multiply the numerator and denominator by the same number to find an equivalent fraction.
We can divide our the numerator and denominator by the same number to find an equivalent fraction.

For example:

1 x 2 = 2 
2 x 2 = 4
In this case I multiplied numerator by 2 and denominator by 2 gives me an equivalent fraction of 2/4

12 / 12 = 1
36 / 12 = 3

In this case I divided the numerator by 12 and the denominator by 12 which gives me an equivalent fraction of 1/3
