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.
