Write down the number given in the figure in digits.

In the figure or the picture that we can see in front of us, there’s an abacus. And we know that an abacus is a way of representing numbers. Each set of beads, and in this case they’re all different-colored beads, represents a different place value column in the number. We can see that there are six different sets of beads here, so we know that it’s a six-digit number. And on this abacus, each place value is labeled, which is really helpful for us.

In the hundred thousands place, there’s one bead. So, that’s 100,000. Then, we’ve got six beads in the ten thousands place, these have a value of 60,000, and then another six beads in the thousands place, or as it’s labeled here the one thousands place. So altogether, the number of thousands in our number is 166,000. And if we’re representing this part of our number using digits, we’d write a one, a six, and a six, followed by a comma, which is to separate the thousands from the next part of our number, the hundreds, the tens, and the ones. There are two beads in the hundreds place, these have a value of 200, three beads in the tens place, so they have a value of 30, and we’ve got five ones. So, the last part of our number reads 235. So, we just need to make sure that we write our two, our three, and our five after that comma.

We’ve used what we know about place value to read this abacus and write the number that it shows in digits. The number is one hundred sixty-six thousand two hundred thirty-five. And we write it in digits as one-six-six-two-three-five. And we’ve used a comma to separate the thousands from the hundreds, tens, and ones.
