Answer:
411
Step-by-step explanation:
Because it has a 4 , 1 , and a 1
meaning the first number can't be 1 so it is automatically a 4.
and then the only 2 numbers left is 2 one's so you have to put them in their also automatically and 4 is asking 1 to round up can it.
411 can't round up,it would round down because 1 is 4 and below so it can't go up and goes down.
so 4 1 1 can't go up the number would have to be 450 to go to 500 but because it is 411 it goes down to 400 because it is rounded to 400.
Hope this helps have a awesome day:)
