A number has been written in the expanded form. What is the number?

This number has 600 plus 10 plus one. We need to take this number and put it in standard form. Our standard form is a digit for the hundreds, a digit for the tens, and a digit for the units.

How many hundreds are there in this number? Six. There are 600s. So we write six in the hundreds place. From there, we need to check the tens place. How many tens are in this number? The number only has one 10. So we write a one in the tens place. And how many units do we have, how many ones? We have one unit. So we write a one in the units place.

When we simplify that and put it altogether, we get 611 — six, one, one.

We also want to know what is the correct unit form of this expanded number? Using the table we’ve just created, we can write out in words to unit form. Starting with our hundreds, we have 600. In our tens, we have one 10. And finally, in our units place, we have one, one. This is how we would use words to write the unit form: six hundreds, one 10, one, one.
