Question

which number below is less than .000065
.0014
.00025
.000075
.0000046
.
.

Answer 1

which one do you think it is?

Answer 2

.0014?

Answer 3

and your reasoning for thinking so?
and please dont say "i guessed"

Answer 4

because it only has 2 zeros?

Answer 5

so firstly for example how you can rewriting these numbers using 10 with exponent

like

,001=10^(-3)

Answer 6

ok.. i understand that

Answer 7

your answer is wrong,

if it helps, move the decimal place over 6 places for each case
the equivalent of multiplying each number by 10^6

so we change the question to
which number below is less than 65
1400
250
75
4.6 .

Answer 8

4.6?

Answer 9

so the corresponding answer would be?

Answer 10

.0000046

Answer 11

or 4.6 x 10^-5

Answer 12

remember for decimals

._ is the tenth place which means x/10

.0_ is the hundredth place which means x/100, so on and so forth

its safe to say, that the more zeros before a number means the smaller the number

and 10^-6 not -5
