Answer:
18.0
Step-by-step explanation:
Note the tenth place value (underlined and bolded): 18.<u>0</u>49
Look at the number to the direct right of the tenth place value (or the hundredth place value in this case). It is a 4. 
Note the rules of rounding. If the number: 
1) is 5 or greater, round up.
2) is 4 or less, round down. 
In this case, it is 4, so you will round down.
18.049 rounded to the nearest tenth is 18.0
