Write 5% as a decimal.
jolli1 [7]
You cannot do it that way.  Make sure the question you wrote is correct, because you would divide 5 by 100, not 100 by 5.  A simple way is to move the decimal point two points to the left.  5% as a decimal is 0.05.  

The answer is false if the question is written this way.
