Question

Mark said that the product of 0.02 and 0.7 is 14.Mark is wrong. What is the product

Answer 1

Hello from MrBillDoesMath!

Answer:

0.014

Discussion:

.02 = 2 * 10^(2)  

and

0.7 = 7 * 10^(-1)

So their product is

2 * 7 * 10^(-2) * 10^(-1)  =

14 * 10^(3) =                                      =>  10^(-3) = 1/10^3 = 1/1000

14/ 1000 =

.014

Thank you,

MrB
