Round the given decimal number to the nearest 100 000 000.
6* 10^8
Practice makes perfect
We want to round the given decimal number and write the result as the product of a single digit and a power of 10.
627 638 538Let's start by rounding the given number to the nearest 100 000 000. Since the digit in the ten millions place is less than 5, we will not modify the digit in the hundred millions place.
6 27 638 538≈ 600 000 000
Finally, we will write the above number as the product of a single digit and a power of 10.
To do so, let's first factor out 6.
