Answer:
18.8
Step-by-step explanation:
18.824 is currently ending in the thousandths place.
For us to ROUND the number, we have to IDENTIFY which place is the TENTH?
18.824
In this situation, the 8 is the TENTH.
FOR US TO ROUND THE TENTH, we look at the thousandths which currently is a 4.
The 4 does not round the hundreds, so our rounded unit becomes:
18.8
