Weight Units - Examples, Exercises and Solutions

The letter T indicates a metric tonne,

One tonne is equivalent to one thousand kilograms,

Therefore, in 7.8 tons there are

1000*7.8 = 7800 kg

First, let's get rid of the fraction:

$\frac{55}{5}=11$

Now we have:

$11\times200kg$

Let's calculate and we get:

$2200kg$

Note that we need the answer in tons, so:

$T=1000kg$

$\frac{2200kg}{1000}=2.2T$

In one kilometer there are 1000 meters,

therefore one meter is one-thousandth of a kilometer.
