Equivalent fractions are fractions that can be simplified down to the same thing.
For example, 9/18 can be simplified down to 1/2
So, 1/2, 3/6, 4/8, 5/10, 6/12, etc are all equivalent fractions because they too can be simplified down to 1/2
i don't really get the part after the (-4,-6) , what did u write there
