You're welcome, using that chart...what do you think the answer could be?

MrMudd183 · Answer

What do you think you need to multiply to go from 28,578 to 0.028578?

ilybre · Answer

To be totally honest my brain is being really dumb right now so I don't know.. I'm so sry

MrMudd183 · Answer

It's alright, if my math is correct you'd have to multiply 28,578 by 1/1000 twice

ilybre · Answer

Ohhh ok thankyou and like are you a teacher or something cause wow

MrMudd183 · Answer

Because when you multiply a number by 1/10,1/100,1/1000,etc., you'll have to move the decimal place over to the left.  But if you were to multiply it by 10,100,1000,etc., you'll have to move the decimal place over to the right.

ilybre · Answer

Just another question what unit would that perhaps be ?

MrMudd183 · Answer

I'm not sure what unit it's in particular, but I know that could be used for Scientific Form

Which is 4*10^2
That expandes is actually 4*100
The exponente on the 10 is how many 0's are behind the 1
