Calculate 24.7 multiplied by
5.9.

So the first thing we’ll actually
do is set up a column multiplication. And what I’ve done here is I’ve
actually as you can see left out the decimal points because we’re gonna deal with
them at the end, so actually multiplying 247 by 59.

So the first stage we’re actually
gonna do is multiply our nine — so our units of our 59 — by each of the numbers in
our 247. So first of all, we’re gonna do
seven multiplied by nine, which is 63. So I actually write a three in our
units and then I actually carry the six, which I’ve put just above so that we can
actually remember that for the next stage.

Next, we have four multiplied by
nine which actually gives us 36. It’s in fact 40 multiplied by nine
which’ll be 360. But in terms of what we’re doing,
this helps us to work out the next step. So we’ve got a 36. But because we actually already had
six carried from the previous multiplication, then we’re gonna have 36 plus six
which is 42. So therefore, I put a two in the
tens column. And I actually carry the four.

Okay, great, so let’s move on to
our next multiplication. So now we actually have two
multiplied by nine which gives us 18. Well, as before, we actually had a
number already carried cause we had four carried on from earlier. So therefore, we have 18 plus four
which gives us 22. So we now write this in in our
thousands and hundreds column. So we’ve got 2223.

So great, we finished multiplying
the nine. We can now move on to the five and
start to multiply that. Well, first of all, we’ve actually
got seven multiplied by five. So this is gonna be 35. However, as we’re actually
multiplying 50 this time cause it’s actually 59, then we’re actually gonna have
seven multiplied by 50 gives us 350. So we put a zero in our units
column and then we’ve got our five in our tens column. And then once again, we carry three
and this time I’ve written it at the top.

Okay, great, so let’s move on to
our next multiplication. We have four multiplied by five,
which gives us 20. But again, we don’t forget the
number that we carried earlier. So we actually had three. So it’s 20 plus three, which is
equal to 23. So therefore, we actually put a
three in our hundreds column and we carry a two.

So now we actually move on to our
final multiplication. So we’ve got two multiplied by
five, which gives us 10, again not forgetting the number we carried from the
previous step. So we’ve actually got two. So it’s 10 plus two, which is gonna
give us 12. So therefore, we actually write the
two in the thousands column and the one in the ten thousands column. So great, so after that
multiplication, we’ve got 12350.

Now, our next stage is to actually
add these together. So we’ve got 2223 plus 12350. So we start with the units
column. Three plus zero is three. Then, we’ve got two plus five is
equal to seven in the tens column, two plus three in the hundreds column which gives
us five, two plus two in the thousands column which gives us a four, and then just
one ten thousands — so that’s one in our ten thousands column.

So brilliant, we’ve multiplied
these numbers together and we’ve got the result 14573. But have we finished here? Well, no, we haven’t because
actually remembering from the beginning question, we actually had 24.7 multiplied by
5.9. And I’ve said we’re gonna deal with
the decimal points later. And this is now where we do
that. Well, if we take a look at the
question, we can see that there are two numbers after the decimal point. So this means that actually in our
final answer, we’ll also need two numbers after the decimal point.

So therefore, we can say that 24.7
multiplied by 5.9 is gonna be equal to 145.73. And we got that because we actually
make sure that we put our two numbers after decimal point, so 145.73.
