What is the answer to round 89658 to the nearest thousand?

Answer 1

89,658 rounded to the nearest thousand is 90,000

When you are rounding the rule is that if the 'bit less' than the target round (in this case 1000) is greater than or equal to 1/2 the target round (in this case 500) then you round up, and if it is less, then you round down.

In this case the 'bit less' is 658, so you round up.
