What is the place value of the digit in brackets in the number 4279?

And in our question, the digit nine is in brackets. Sometimes by reading a number out loud as we read the question out, it can give the answer. So what we’ll do is pretend that we haven’t just heard the name of the number, and we’ll just imagine that we’ve just seen it. We know it has four digits, four, two, seven, and nine. And, the digit nine is in brackets. This is just to show us that this is the digit that the question’s talking about. We need to say what the place value of the digit in brackets is. In other words, what is the place value of the digit nine in this number?

Where a digit belongs in a number or its place gives it its value and tells us what it’s worth. And, the four different places that are in a four-digit number are worth units, this is another word for ones so we’ll put an o there just to remind us, tens, hundreds, and finally the value of the largest digit is thousands. These are the different values of the four different places in a four-digit number.

Let’s put our number four, two, seven, nine into our place value grid. Four, two, seven, nine. Once we know the place value of each digit, we can then read our number. Each digit has a value then. Four thousands, we know this because the digit four is in the thousands place. Then, we also have two hundreds, seven tens, which has a value of 70, and then nine units or nine ones. We can now read our number, 4279. As we’ve just said, the value of the nine digit is nine units or nine ones. The digit that was written in brackets in the question was nine. And the place value of the digit nine in 4279 is units.
