Answer:
21,300
Explanation:
Since the two is next to the five you round up
In a decimal, rounding a hundredth means 1/100 or 0.01. So to answer your question the answer is 21.25. The 3 after 5 will not change the number as 3 is less than 5 so the 5 will stay the same. We only round the hundredth and not the tenth or thousandth.
