Practice makes perfect
We want to round the given decimal number to the nearest hundredth.
12.89503Since the digit in the thousandths place is greater than or equal to 5, we will increase the digit in the hundredths place by one. Since this digit is 9, it means that the previous digit should be increased by one and 9 changed to 0.
12. 8 9 503 ≈ 12. 9 0
Finally, let's simplify our answer.
12.90 = 12.9
