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 Help ✎ (−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.

’Based on the statements made by Stephanie and Stacy, When Multiplying any value by a decimal or fraction lesser than 1, the result obtained would be lesser than the number which is multiplied. Hence, Stephanie ls correct.

Take for instance :

10 × 2 means 10 in 2 places = 20

10 × 1/2 means half of 10 = 5

This shows that, multiplying by fractions less than one is equivalent to dividing the first number by the denominator of the fraction.

10 × 1/2 = 10/2 = 5

Therefore, Multiplying by a fraction less than 1 yields a value less than you started with.
