I'm not sure if this helps but in physics if I say that something is 1cm long it could be 0.1cm long or 1.9cm long. If I say that something is 1.00cm long or means I have a ruler that measures mm. So the amount of decimal places indicates the precision of the measurement. Hope this helps
The more precise your instruments of measurement are, the less percentage of error you will have.
Accuracy. How close you are to your expected value. Precision. How close together you values are.
It is close to becoming an exact answer too a whole number!!
i really don't no if i find out I'll tell u thx hope this helps!
If you indicate that the mass of an object is 17.2 grams then this implies that you have measured its mass to be somewhere between 17.195 and 17.205. If, however, you indicate a mass of 17.2153 then it will be understood that you have measured the mass to be between 17.21525 and 17.21535. In short, the number of decimal points indicates the precision of the measurement (even when those digits are zeroes).
