Round 8,764 to the nearest hundred
Zigmanuir [339]

Answer: 8,800

Step-by-step explanation:

Since the hundredth place is 764 we will round up to 800

which will give you 8,800!

Tip: Rounding the number up only takes place if the last two digits in the number are 50 or above.

If not, Round down if the last two digits in the number are 49 or below.

IF the last digits are 00 no rounding takes place.
