Need to round 363 to the nearest ten and hundred

1- Rounding to the nearest ten:
When we round a number to the nearest ten, we check the digit in the units position:
If the digit is less than 5, then the number in the tens remains the same and all numbers after that are turned to zero
If the digit is equal to or more than 5, then we add one to the tens digit and turn all numbers after that into zero.

In the given we have:
363, the number in the units position is 3, this means that rounding to the nearest tens will give us 360.

2- Rounding to the nearest hundreds:
When we round a number to the nearest hundreds, we check the digit in the tens position:
If the digit is less than 5, then the number in the hundreds remains the same and all numbers after that are turned to zero
If the digit is equal to or more than 5, then we add one to the hundreds digit and turn all numbers after that into zero.

In the given we have:
363, the number in the tens position is 6, this means that rounding to the nearest tens will give us 400.

Hope this helps :)
