Answer:
2.5048
Explanation:
the fourth decimal place of 2.5047754593 is the first seven.
to round take the next decimal to the right of the seven and determine if it is 0-4 or 5-9. in this case it is 7 so it will go in the second catagory
so that means to round up instead of keeping the same number. so the seven becomes an eight and the rest of the numbers go away
hope i explained well! :)
