3-74. mentally calculate the following products.  use the rule for decimal multiplication to write an equation in which the decimal point is written in the correct location.  homework ✎ (−0.04)(−0.1)  (0.03)(−0.02)  (0.7)(0.4)  stacey said, “stephanie, look at my answer to the last problem, 0.7 · 0.4 = 0.28.   usually when i multiply, i get a bigger answer than the numbers i start with.   twenty-eight hundredths, 0.28, is less than either 0.4 or 0.7.  i must have made a mistake.” stephanie  responded, “well, one half times one half is one fourth, and one fourth is less then one half.  i think when you multiply by a fraction or decimal less than one, you get less than you started with.” write a sentence or two about who you think is correct and why.
