Answer:
170.6
Step-by-step explanation:
The tenth place is the first number to the right of the decimal place.
Since we have to round to the tenth place, we can round 170.55 by looking at hundredths place. If the 5 in the hundredths place is greater than or equal to 5 than the tenth place rounds up and if it is less than 5 than the tenth place rounds down. In this case 170.55 would round up to 170.6.
