72.56 x Rewritten x 100 = 7, x Rewritten x 10 = ***Remember that the decimal does not hold a place value and a number can’t be put in its position

18.49 / 1,000 **the above symbol is being used for a division sign Rewritten with zeros inserted into appropriate places / 1,000 = / Rewritten / 10 = or Since a zero at the end of decimal number has no value, we do not have to include it
