Question

Which is the best estimate of 5 5/6 - (1 1/4 + 3 7/8)​

Answer 1

Answer:

Step-by-step explanation:

"Best estimate' doesn't happen automaticallly, because you have to define "best" in this context.  We could merely round all numbers and work with the results:  

For example, starting with the work inside parentheses, we have:

5 5/6 - (1 + 4) = 5 5/6 - 5.  We must round 5 5/6 up to 6.  Then the "best estimate' is 6 - 5, or just 1.
