Write seven hundred and ninety-five million, eight hundred and fifty-six thousand, three hundred and ninety-five in digits.

This problem gives us a large number written in words. And we need to write it in digits. The first thing to notice about our number is the way it’s been written in words is it splits neatly into three parts. And they’re separated by commas. Our first part shows the number of millions. We have hundred millions, ten millions, and millions. We’ll come back to these in a second.

The next part of our number describes the number of thousands, eight hundred and fifty-six thousand. We have hundred thousands, ten thousands, and thousands. And the final three digits in our number are part of a group we’ll call the ones. These are our hundreds, tens, and ones. Now the commas that’ve been written in between these words help us to say each section separately. And they help us to read the number more clearly. So when we write the number using digits, we’ll use commas again. And this will help us to read the number more clearly. Let’s read through the number carefully now. And we’ll write each digit in the correct place on our place value grid.

First, the number of millions, seven hundred and ninety-five million. So we write a seven in the hundred millions place and nine in the ten millions place that represents nine ten millions or 90 million and then a five in the millions place, 795 million. On to the thousands group, we have eight hundred and fifty-six thousand. So that’s eight hundred thousands, five ten thousands, which has a value of 50 thousand, and six thousands, 856 thousands.

And finally, the group we call our ones, three hundred and ninety-five. So that’s three in the hundreds column, nine in the tens column, representing 90, and five ones, 395. Look at what our nine-digit number looks like if we don’t put any commas or small spaces in between the groups. It’s very difficult to read. So as part of our answer, we’re going to include commas. We used our knowledge of place value to help convert the number that was written in words into digits. 795,856,395 written in digits can be written as seven, nine, five, eight, five, six, three, nine, five.
