Answer: 9.0000
Step-by-step explanation:
8.9799. To round to the tenths, take a look at the hundredths digit, 7. If digit is ≥5 (at least 5), round up and if lower than 5, round down. 7 > 5, so we choose the first scenario. We round up. 0.9 is the last tenth in an integer, so we get a new ones digit as well.
8.97 ==> 9.00
