Question

Anna truncated the decimal expansion of x to find the best approximation. On a number line, the location of x is between 10.9 and 11.1. What is the BEST estimate of the value of x? A) 115 B) 118 C) 120 D) 125

Answer 1

Answer:

Well to estimate a decimal the best option would be to round it to.

10 or 11 (For 10.9)

11 (For 11.1)

and since two of them equal 11. 

The estimation would be 11.

I hoped this helped.
