This isn't a specific HW problem, its just something I keep tripping over for some reason so I guess it qualifies as HW. OK so, for example the number 1.5 has 2 sig fig . But if you compare that to another number with 3 sigfigs, like 1.58, then arent they actually equal? What is confusing me, is what exactly does 1.5 imply about tenths and the the hundredths places? They are insignificant, but how do you determine if 1.58 is greater or lessor than 1.5?
The Attempt at a Solution
I think the numbers are equal but I am not seeing the reasoning. thanks
