Charlie is evaluating the product of 0.09 and 0.05. he multiplies, and before placing the decimal, arrives at an answer of 45. after considering the decimal placement, what is charlie’s final answer? 0.0045

The actual answer is C. 0.45 because 0.09*0.05=0.45 because 9*5=45, 5*0=0, and 5*0=0 but 5*0+4=4 so you have 0.45
