Write in centimeters: eight meters
and five centimeters.
In this question, we’re given a
measurement. Now we might think at first glance
that this looks like two measurements because not only can we see a number of
meters, but also some centimeters too. But this is one single
measurement. It just means slightly more than
eight meters, eight meters and five centimeters. Now at the moment, this measurement
has been written, as we’ve said already, in meters and also centimeters. But we can convert this measurement
so that we write it just in centimeters, which is exactly what this question asks us
to do. To help us, we can split up or
partition eight meters five centimeters. And we can split it into eight
meters and five centimeters.
Now our question asks us to write
the whole measurement in centimeters. And at the moment, part of it
already is in centimeters, so we can ignore this for a moment. Let’s concentrate on the part that
isn’t in centimeters. How can we convert eight meters
into centimeters? Is there a fact we can use to help
us? We know that one meter is the same
as 100 centimeters, and so eight meters must be the same as eight lots of 100
centimeters or 800 centimeters. Now that we’ve converted our number
of meters into centimeters, both parts are written in centimeters. So we just need to add the two
parts back together again. 800 centimeters plus another five
centimeters equals 805 centimeters. We can write eight meters and five
centimeters in centimeters as 805 centimeters.
