... We know that Mg has a +2 charge, and PO4 has a -3 charge. These two numbers do not add up to zero. Thus, we find a least common denominator and find out what we must multiply each number by to get this result. Out LCD is 6, thus we multiply +2 by 3 and -3 by 2. This results in +6 and -6 cancelling o ...
