Sam solved a multiplication problem as shown below. He thought that it was an easy problem but did not get it right. What did he do wrong? Identify and correct Sam's mistake.

What is twelve point zero three times zero point seven six? Sam writes twelve point zero three and zero point seven six vertically to multiply them. He multiplies six by twelve point zero three to get seven two one eight. Then he adds a zero as a placeholder and multiplies seven by twelve point zero three to get eight four two one. He adds the partial products to get nine one four two eight. Finally, he moves the decim
