Question

Round each to the place indicated.
1) 8,632,051 rounded to the nearest billion

Answer 1

1,000,000,000

Explanation:

To round you have to look at the number to the right of what you're rounding to which in this case is the 8. When rounding if the number is between 1 and 4 you round down and if the number is between 5 and 9 you round up. Since it is 8 you round up and the nearest billion above the current number is 1 billion.

I hope this helps and please don't hesitate to ask if there is anything still unclear!

Answer 2

9,000,000

Explanation:

To round numbers you look at the number to the RIGHT of the place value you want to round to.

In this case, you want to round to the nearest million and 8 is in the millions place.

Look to the right of 8, and it is 6. If the number is 5 or more then round the number in the millions place UP, if it is 4 or less round the number in the millions place DOWN.

Since 6 is 5 or more, make the 8 a 9 and all the remaining numbers after that become zeros.

8,632,051 becomes 9,000,000. This makes sense because this is 9 million, with no other numbers that aren't in the millions place.
