To what place is 101 accurate

Question

 The answer choices are hundreds tens ones or tenths

Answer 1

As stated by the tutors, 101 is accurate to the ones place.  If this is a physical measurement x, that means you know the measurement to within ±1 of 101, or

 

x = 101 ± 1,

 

which really means you only know that the true value of x lies in the range of 100 to 102.  By the way, if x was 101.0, then you know x lies between 100.9 and 101.1, which is a more precise measurement.

 

 

Answer 2

All you need to do is remember the place value of the number you have. 

Remember the most far right digit and look for a decimal point.

If there is no decimal point, then the first place will be the ones place, that will be your most accurate value.

Answer 3
