The basic property of fraction

Multiplying the numerator and denominator of a fraction by the same non-zero number, the results of the new fraction is said to be equivalent to the original fraction. Dividing the numerator and denominator of a fraction by the same non-zero number will also yield an equivalent fraction. The word equivalent means that the two fractions have the same value.

For example:

2	=	2·2	=	4	;
3		3·2		6

or

6	=	6:2	=	3	.
8		8:2		4
