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

Hello from MrBillDoesMath!

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

no this is a nonlinear negative

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
