66 rounded to the nearest hundred and ten

66 when rounded to the nearest hundred is 100 and when rounded to the nearest ten is 70

A rounded number has the same value as the number an individual start with, but it is less exact.  

For example, 345, when rounded to the nearest hundred is 300. This is simply because the 345 is closer in value to 300 than the value 400. If we decide to round off to the nearest dollar, $2.89 will become $3.00 just because $2.89 is very close to $3 than to $2.

These are the general rules for rounding:

In a case the number you are rounding off is followed by 5, 6, 7, 8, or 9, then round the number up. For example, 37 when rounded to the nearest ten is 40. And in a case the number you are rounding is followed by 0, 1, 2, 3 or 4, then round the number down. For example, 33 when rounded to the nearest ten is 30.

When you are rounding a number, firstly you need to ask yourself what you are rounding to. Generally, numbers can be rounded to the nearest ten, nearest hundred, nearest thousand etc.  

For example, 4.826  

When rounded to the nearest ten is 4.830

When rounded to the nearest hundred is 4,800

And when rounded to the nearest thousand is 5000
