Look at these numbers. 41, 62, 34. Which is the greatest number? Which is the smallest number?
We can see three two-digit numbers
here. And they’re shown in two different
ways; they’re shown as a number but also using tens and ones. We’ve got the number 41, 62, and
34. And we’re asked two questions about
these numbers. Which of them is the greatest
number? In other words, which is
largest? And then, which is the smallest
number? You know, if we put these numbers
in order, say, from greatest to smallest, we’d be able to spot which number was the
greatest and which was the smallest. Why don’t we try doing that?
Now, when we put two-digit numbers
in order, we need to compare the tens and the ones. A ten is worth a lot more than a
one. So, we need to compare the tens
first; they’re more important. The number 41 contains four
tens. There are six tens in 62, and there
are only three tens in the number 34. The number of tens here are all
different. We don’t even need to look at the
ones. We could put these numbers now in
order. Which is the largest number? Well, six tens is larger than four
tens and is also larger than three tens.
So, if we’re putting our numbers in
order from greatest to smallest, we need to start with the number 62. We’re now left with 41 and 34. Which is the next largest number of
tens? Well, we know that four tens is
greater than three tens. So, 41 is the next largest number
in our list. And this means the smallest number
must be 34. This is the number with the least
amount of tens. Now, we’ve compared the tens. All we need to do is to use our
order to answer the two questions.
The greatest number here is 62;
it’s the number with the most tens. And the smallest number here is the
number 34; this is the number with the least tens.
