Approximate the value 66 to nearest hundredth

Tip: Adding zeroes to the left of a whole number or the right of a decimal does not change the value. 

Ok, so we need to round 066 to the nearest hundred. 
Since 0 is in the hundreds place, we need to look at the number to the right of it (6), and determine if we need to round up or down. 

If the number is 4 or less, we need to round down, if the number is 5 or more, then we need to round up. Since the number is 6, we'll round up. 

The answer is 100
