Round 1627187 to the nearest
ten.
The first step is to figure out
which digit is in the tens place. The tens place is to the left of
the units place. In this case, it would be the
eight. In order to round to the nearest
10, we’ll need to look at the digit to the right of the tens place, in the units
place. In our case, we have a seven
here.
For rounding, we have two
cases. We have the case that the value to
the right of the digit you’re rounding is less than or equal to four. In that case, you round down. The second case is when the digit
to the right of the number you’re rounding is greater than or equal to five. In that case, you would round
up.
We’re dealing with the seven. Seven is greater than or equal to
five. We need to follow the second case
and round up. In that case, the eight rounds up
to nine. Everything to the right of the
tens place becomes a zero and everything to the left of the tens place stays
exactly the same.
By rounding to the nearest 10, our
new value is 1627190.
