Use the digits 1-7 to create a seven-digit number that can be rounded to 6,300,000.

There are many ways to figure this out. One way is 6,275,431. You just need to start the number with a 6, followed by a 2 and 5 or 7, then you can mix up the rest of the numbers any way you want.

To create a seven-digit number that rounds to 6,300,000 using the digits 1-7, start with '6' followed by '2' or '3', and arrange the remaining digits wisely. For example, numbers like 6,274,531 and 6,345,721 fit this criterion as they round correctly. They stay within the necessary range for rounding to millions.
