1000 grammes
1 / 1000 of a gramme
1000 kilogrammes
= 1 000 000 grammes
|
| |
|
1 x kilometre is 1000 metres |
So we divide by 1000 |

Move the decimal point to
the left of the 3 noughts

There are 100 centimetres
in a metre.
There are 1000 millimetres
in a metre, so
There is 10 millimetres
in 1 centimetre.
So divide this sum
by 10
-----------------------------

950 mm = 950 = 95 cm
00000000-----

There are 1000 millitres in 1 litre,
so, to convert from litres to millilitres multiply by 1000.

1 metric tonne is 1000 kilogrammes,
so, to convert from kilogrammes to tonnes divide by 1000

5ft 5" = 65"
&
1" = 2.54 cm
Remember the 2 decimal point has
to move 2 places, so the answer would be
00000 165 . 10
This is true but we must also round the number off, because the
number is over half of the whole number, we call it :
166 is the correct answer.
-----------------------------

5ft = 12"
x 5 = 60"
60" + 5" = 65"

3.81m = 381cm = 150"
1.27m = 127cm = 50"
So the carpet is 150" x
50"
-----------------------------
|
Convert the room
figures into inches:
10ft 6" = 126"
10 x 12 = 120 + 6 = 126
3ft 6" = 42"
3 x 12 = 36 + 6 = 42

The easy way to
solve this, is to cancel the noughts. Remember when you cancel
a nought from the top, do the same at the bottom.
Now you should
of had the video has the best deal of the 2, with 20% discount
as apposed to the TV with 12.5%.
