#### Answer

$$Hundred=0$$ $$Ten=10$$ $$Unit=8$$ $$Tenth=8.2$$ $$Hundredth=8.17$$ $$Thousandth=8.172$$

#### Work Step by Step

Hundreds place = nearest 100 (in the whole numbers) So, 8.171717 rounded to the hundreds place is $0$ Tens place = nearest 10 (in the whole numbers) So, 8.171717 rounded to the tens place is $10$. Unit = nearest 1 (in the whole numbers) So, 8.171717 rounded to the unit is $8$. Tenths place = to the nearest 10 (in the decimals) So, 8.171717 rounded to the tenth place is $8.2$ Hundredths place = to the nearest 100 (in the decimals) So, 8.171717 rounded to the hundredths place is $8.17$ Thousandths place = to the nearest 1000 (in the decimals) So, 8.171717 rounded to the thousandths place is $8.172$
