Answer:
819560
Explanation:
the rules of rounding are simple.
since we're rounding to the nearest ten, we take a look at the ones place. if the one is a five or above, we go ahead and round. if it's lower than five, then turn it into a zero, and all the other places stay the same.
the ones place is a nine, so we would round up. turn the one into a zero, and turn the five in the tens place into a six. all the other numbers stayed the same. now, let's just imagine that the nine in the ones place is a three. we round down. turn it into a zero, and all the other numbers stay the same.
hope this helped :)
