Thank you!

To write 768,390 as a decimal, you need to know the place value of each digit in the number.

Starting from the leftmost digit, which is 7, it occupies the hundreds of thousands place (or 700,000). The next digit, 6, occupies the ten thousands place (or 60,000). The digit after that, 8, occupies the thousands place (or 8,000). The digit 3 occupies the hundreds place (or 300). The digit 9 occupies the tens place (or 90), and finally, the last digit 0 occupies the ones place.

To form the decimal, you'll divide each place value by the corresponding power of 10 and sum them up.

So, 768,390 can be written as:

(7 x 100,000) + (6 x 10,000) + (8 x 1,000) + (3 x 100) + (9 x 10) + (0 x 1)

= 700,000 + 60,000 + 8,000 + 300 + 90 + 0

= 768,390

Therefore, as a decimal, 768,390 remains the same. It is not 7.6839, but rather 768,390.
